Prove that limits in distribution are unique. That is, suppose X, Y, X1, X2,... are all real valued random variables and (X.):=1 converges in distribution to both X and Y. Show X and Y have the same distribution, i.e. Px = Py. You may use that a cumulative distribution function has at most countably many discontinuities (as noted in the proof of Proposition 1.2 in Lecture 25). You may also use the fact that if S C R is countable, then any 8 € S is the limit of a decreasing sequence (cn)CR\S. Hint: Start by showing that the CDFs of X and Y agree.
The CDFs of X and Y agree for all x, and hence X and Y have the same distribution, i.e., P(X = A) = P(Y = A) for all events A.
What is convergence?In mathematics, convergence is the feature of certain infinite series and functions of getting closer to a limit when an input (variable) of the function changes in value or as the number of terms in the series grows.
To prove that limits in distribution are unique, let's assume that (\(X_n\)) converges in distribution to both X and Y. We need to show that the cumulative distribution functions (CDFs) of X and Y agree, i.e., P(X ≤ x) = P(Y ≤ x) for all x.
Let \(F_X\)(x) and F_Y(x) denote the CDFs of X and Y, respectively.
Since (\(X_n\)) converges in distribution to X, we have the following convergence:
lim(n→∞) P(\(X_n\) ≤ x) = P(X ≤ x)
Similarly, since (\(X_n\)) converges in distribution to Y, we have:
lim(n→∞) P(\(X_n\) ≤ x) = P(Y ≤ x)
Therefore, we can write:
lim(n→∞) P(\(X_n\) ≤ x) = P(X ≤ x) = P(Y ≤ x)
Now, let's consider the set S = {x ∈ R: P(X ≤ x) ≠ P(Y ≤ x)}. We want to show that S is empty, which means that the CDFs of X and Y agree for all x.
Assume S is not empty. Since a CDF has at most countably many discontinuities, S is countable.
Now, for each x ∈ S, we can construct a decreasing sequence (\(c_n\)) in R\S such that lim(n→∞) \(c_n\) = x. This is possible because R\S contains infinitely many elements.
Using the fact that (\(X_n\)) converges in distribution to both X and Y, we have:
lim(n→∞) P(X_n ≤ \(c_n\)) = P(X ≤ x) (1)
lim(n→∞) P(X_n ≤ \(c_n\)) = P(Y ≤ x) (2)
Taking the limit as n approaches infinity in both equations, we get:
lim(n→∞) P(X ≤ x) = P(X ≤ x)
lim(n→∞) P(Y ≤ x) = P(Y ≤ x)
This implies that P(X ≤ x) = P(Y ≤ x) for all x ∈ S.
However, since S is countable, this implies that P(X ≤ x) = P(Y ≤ x) for all x ∈ R.
Therefore, the CDFs of X and Y agree for all x, and hence X and Y have the same distribution, i.e., P(X = A) = P(Y = A) for all events A.
Hence, we have shown that limits in distribution are unique, as required.

A population has a mean of 800 and a standard deviation of 200. Suppose a sample of size 400 is selected and
x
is used to estimate μ. (Round your answers to four decimal places.)
(a)____
What is the probability that the sample mean will be within ±5 of the population mean?
(b)___
What is the probability that the sample mean will be within ±10 of the population mean?
a. The probability that the sample mean will be within ±5 of the population mean is the area under the normal curve between these two z-scores. b. The lower bound z-score is (-10 - 0) / 10 = -1, and the upper bound z-score is (10 - 0) / 10 = 1. We can use the same normal distribution table or technology to find the probability associated with these z-scores.
(a) To find the probability that the sample mean will be within ±5 of the population mean, we can use the Central Limit Theorem (CLT) and the properties of a normal distribution.
The sample mean, is an unbiased estimator of the population mean, μ. According to the CLT, the distribution of sample means approaches a normal distribution with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size.
= 200 / √400
= 200 / 20
= 10
To find the probability that the sample mean will be within ±5 of the population mean, we can standardize the interval using the z-score:
For the lower bound (-5), the z-score is (-5 - 0) / 10 = -0.5.
For the upper bound (+5), the z-score is (5 - 0) / 10 = 0.5.
We can now use a standard normal distribution table or technology (such as a calculator or statistical software) to find the probability associated with the z-scores -0.5 and 0.5. The probability that the sample mean will be within ±5 of the population mean is the area under the normal curve between these two z-scores.
(b) To find the probability that the sample mean will be within ±10 of the population mean, we follow the same steps as in part (a).
The lower bound z-score is (-10 - 0) / 10 = -1, and the upper bound z-score is (10 - 0) / 10 = 1. We can use the same normal distribution table or technology to find the probability associated with these z-scores.
Note: Since the question mentions rounding answers to four decimal places, please use the appropriate table or technology to obtain the precise probabilities for parts (a) and (b).

a sample from a refuse deposit near the strait of magellan had 60% of the carbon-14 of a contemporary sample. how old was the sample. round to the next whole year.
The age of the decaying sample according to the decay formula is 42,009 years.
The rate of radioactive carbon-14 decay depends on the function
\(A(t) = A_{0} e^{-0.0001216t}\)
where \(A_{0}\) is the quantity found in living plants and animals, t is in years, and is the age.
60% of the carbon-14 of a current-day sample was present in a sample taken from a refuse deposit close to the Strait of Magellan. We need to evaluate the age of the sample,
A = 60 % of \(A_{0}\) = (3/5)\(A_{0}\)
Putting this in the decay equation, we have,
\(\frac{3}{5} A_{0} = A_{0} e^{-0.0001216t}\\\\ 0.6= e^{-0.0001216t}\\ \\ln0.6 = -0.00001216t\\\\-0.51082 = -0.00001216t\\\\t = 42,008.68\)

in a parking lot, (3)/(4) of the cars are red and (1)/(8) are blue. how much greater is the fraction of red cars than the fraction of blue cars? (a) (5)/(8) b (1)/(4) c (1)/(6) d (1)/(3)
Answer: (a) Red cars are 5/8 greater than the fraction of blue cars
Step-by-step explanation:
To determine the difference in fractions between the red cars and blue cars in the parking lot, we need to calculate the fraction of red cars and the fraction of blue cars and then find the difference between them.
Given:
(3/4) of the cars are red
(1/8) of the cars are blue
To find the difference between the fractions, subtract the fraction of blue cars from the fraction of red cars:
(3/4) - (1/8)
To subtract fractions, we need a common denominator. In this case, the least common multiple of 4 and 8 is 8.
Rewriting the fractions with a common denominator:
(6/8) - (1/8)
Now we can subtract the numerators:
(6 - 1)/8 = 5/8
Therefore, the fraction of red cars is (5/8) greater than the fraction of blue cars.
So, the answer is (a) (5/8).
Answer:
5/8
Step-by-step explanation:
To find the answer, you should subtract the fraction of the blue cars from that of the red ones.
\( \frac{3}{4} - \frac{1}{8} = \frac{5}{8} \)
A rectangular parallelepiped has sides 3 cm, 4 cm, and 5 cm, measured to the nearest centimeter.a. What are the best upper and lower bounds for the volume of this parallelepiped?b. What are the best upper and lower bounds for the surface area?
The best lower bound for the volume is 24 cm³, and the best upper bound is 120 cm³ and the best lower bound for the surface area is 52 cm², and the best upper bound is 148 cm².
a. To determine the best upper and lower bounds for the volume of the rectangular parallelepiped, we can consider the extreme cases by rounding each side to the nearest centimeter.
Lower bound: If we round each side down to the nearest centimeter, we get a rectangular parallelepiped with sides 2 cm, 3 cm, and 4 cm. The volume of this parallelepiped is 2 cm * 3 cm * 4 cm = 24 cm³.
Upper bound: If we round each side up to the nearest centimeter, we get a rectangular parallelepiped with sides 4 cm, 5 cm, and 6 cm. The volume of this parallelepiped is 4 cm * 5 cm * 6 cm = 120 cm³.
Therefore, the best lower bound for the volume is 24 cm³, and the best upper bound is 120 cm³.
b. Similar to the volume, we can determine the best upper and lower bounds for the surface area of the parallelepiped by considering the extreme cases.
Lower bound: If we round each side down to the nearest centimeter, the dimensions of the parallelepiped become 2 cm, 3 cm, and 4 cm. The surface area is calculated as follows:
2 * (2 cm * 3 cm + 3 cm * 4 cm + 4 cm * 2 cm) = 2 * (6 cm² + 12 cm² + 8 cm²) = 2 * 26 cm² = 52 cm².
Upper bound: If we round each side up to the nearest centimeter, the dimensions become 4 cm, 5 cm, and 6 cm. The surface area is calculated as follows:
2 * (4 cm * 5 cm + 5 cm * 6 cm + 6 cm * 4 cm) = 2 * (20 cm² + 30 cm² + 24 cm²) = 2 * 74 cm² = 148 cm².
Therefore, the best lower bound for the surface area is 52 cm², and the best upper bound is 148 cm².

Solve the given system of equations using either Gaussian or Gauss-Jordan elimination. (If there is no solution, enter NO SOLUTION.) √2x + 2z = 5 y + √2y - 3z = 3√2 -y + √2z = -3 [x, y, z]
The given system of equations can be solved using Gaussian or Gauss-Jordan elimination. Therefore, the solution to the system of equations is x = 1, y = 2√2, and z = -1.
The solution to the system of equations is x = 1, y = 2√2, and z = -1.
We can start by applying Gaussian elimination to the system of equations:
Row 1: √2x + 2z = 5
Row 2: y + √2y - 3z = 3√2
Row 3: -y + √2z = -3
We can eliminate the √2 term in Row 2 by multiplying Row 2 by √2:
Row 1: √2x + 2z = 5
Row 2: √2y + 2y - 3z = 3√2
Row 3: -y + √2z = -3
Next, we can eliminate the y term in Row 3 by adding Row 2 to Row 3:
Row 1: √2x + 2z = 5
Row 2: √2y + 2y - 3z = 3√2
Row 3: (√2y + 2y - 3z) + (-y + √2z) = (-3√2) + (-3)
Simplifying Row 3, we get:
Row 1: √2x + 2z = 5
Row 2: √2y + 2y - 3z = 3√2
Row 3: √2y + y - 2z = -3√2 - 3
We can further simplify Row 3 by combining like terms:
Row 1: √2x + 2z = 5
Row 2: √2y + 2y - 3z = 3√2
Row 3: (3√2 - 3)y - 2z = -3√2 - 3
Now, we can solve the system using back substitution. From Row 3, we can express y in terms of z:
y = (1/3√2 - 1)z - 1
Substituting the expression for y in Row 2, we can express x in terms of z:
√2x + 2z = 5
x = (5 - 2z)/√2
Therefore, the solution to the system of equations is x = 1, y = 2√2, and z = -1.

every polynomial function of odd degree with real coefficients will have at least
Every polynomial function of odd degree with real coefficients will have at least one real root or zero.
This statement is known as the Fundamental Theorem of Algebra. It states that a polynomial of degree n, where n is a positive odd integer, will have at least one real root or zero.
The reason behind this is that when a polynomial of odd degree is graphed, it exhibits behavior where the graph crosses the x-axis at least once. This implies the existence of at least one real root.
For example, a polynomial function of degree 3 (cubic polynomial) with real coefficients will always have at least one real root. Similarly, a polynomial function of degree 5 (quintic polynomial) with real coefficients will also have at least one real root.
It's important to note that while a polynomial of odd degree is guaranteed to have at least one real root, it may also have additional complex roots.
The Fundamental Theorem of Algebra ensures the existence of at least one real root but does not specify the total number of roots.
In summary, every polynomial function of odd degree with real coefficients will have at least one real root or zero, as guaranteed by the Fundamental Theorem of Algebra.
