The given statement "We can represent the pdf of a discrete random variable x with a histogram." is True, because histograms are often used to graphically represent the distribution of a discrete random variable.

In a histogram, the x-axis represents the different possible values of the discrete random variable, and the y-axis represents the probability or frequency of observing each value. The bars in the histogram represent the probabilities or frequencies of the different values, and the height of each bar corresponds to the probability or frequency.

Note that for a discrete random variable, the PDF is actually a probability mass function (PMF), which gives the probability of each possible value of X. However, the histogram can be used to represent the PMF by scaling the heights of the bars appropriately so that they represent probabilities rather than frequencies.

(a) When performing an ANOVA with the data the alternative hypothesis is at least two of the restaurants have different mean delivery times.

(b)75.8

Analysis of variance. or ANOVA, is a statistical method that separate observed variance data into different components to use for additional tests. A one way ANOVA is used for three or more groups of data, to gain information about the relationship between the dependent and independent variables.

The ANOVA table shows how the sum of squares are distributed according to source of variation, and hence the mean sum of squares.

It is given that a pizza lover wants to compare the average delivery times.

Therefore the null hypothesis and alternate hypothesis implies that,

H₀ =  all restaurants have equal mean delivery time

Hₐ = at least two restaurants have different two deliveries

Hence the alternate hypothesis for performing an ANOVA with the data is at least two of the restaurants have different mean delivery times.

The alternate hypothesis (Hₐ) defines that there is a statistically important relationship between two variables. Whereas null hypothesis states that is no statistical relationship between the two variables.

Answer:

Explained below.

Step-by-step explanation:

The data provided is as follows:

S = {31.5, 36.0, 37.8, 38.5, 40.1, 42.2, 34.2, 36.2, 38.1, 38.7, 40.6, 42.5, 34.7. 37.3, 38.2, 39.5, 41.4, 43.4, 35.6, 37.6, 38.4, 39.6, 41.7, 49.3}

Compute the mean and standard deviation as follows:

\(\mu=\frac{1}{n}\sum X=\frac{1}{24}\times [31.5+36.0+37.8+...+49.3]=38.88\\\\\sigma=\sqrt{\frac{1}{n-1}\sum (X-\mu)^{2}}=\sqrt{\frac{1}{24-1}\times 299.639584}=3.61\)

(a)

Compute the​ z-score corresponding to the individual who obtained 32.3 miles per gallon as follows:

\(z=\frac{X-\mu}{\sigma}\)

  \(=\frac{32.3-38.88}{3.61}\\\\=-1.823\)

Thus, the z-score corresponding to the individual who obtained 32.3 miles per gallon is -1.823.

(b)

The data set arranged in ascending order is:

S = {31.5 , 34.2 , 34.7 , 35.6 , 36 .0, 36.2 , 37.3 , 37.6 , 37.8 , 38.1 , 38.2 , 38.4 , 38.5 , 38.7 , 39.5 , 39.6 , 40.1 , 40.6 , 41.4 , 41.7 , 42.2 , 42.5 , 43.4 , 49.3}

The set consists of 24 values.

The first and third quartile are:

\(Q_{1}=[\frac{n+1}{4}]^{th}\ obs.=[\frac{24+1}{4}]^{th}\ obs.=12.5^{th}\ obs.=\frac{36.2+ 37.3}{2}=36.75\\\\Q_{3}=[\frac{3(n+1)}{4}]^{th}\ obs.=[\frac{3(24+1)}{4}]^{th}\ obs.=18.75^{th}\ obs.=\frac{40.6+41.4}{2}=41\)

Thus, the value of Q₁ is 36.75 and Q₃ = 41.

(c)

Compute the inter-quartile​ range as follows:

\(IQR=Q_{3}-Q_{1}=41-36.75=4.25\)

The inter-quartile range is 4.25.

The inter-quartile range is the amount of data that is contained within the middle 50% of a set of observations, when arranged in order. It is the distance between the first and third quartile.

(d)

Compute the values of lower and upper fences as follows:

\(\text{Lower fence}=Q_{1}-1.5\times IQR=36.75-(1.5\times 4.25)=30.375\approx 30.38\\\\\text{Upper fence}=Q_{3}+1.5\times IQR=41+(1.5\times 4.25)=47.375\approx 47.38\)

Any values that are less than the lower fence or more than the upper fence are considered as outlier.

Consider the arranged data set.

Only one value is more than the upper fence, 47.38, i.e. 49.3.

So, yes there is one outlier, i.e. 49.3.

Their present ages are 12 years and 16 years.

Step-by-step explanation:

Given that,

Ages of Raju and Ravi are in the ratio 3:4 .Four years from now the ratio of their ages will be 4:5.

Let their present age is 3x and 4x.

Ages after four years from now will be:

\(\dfrac{3x+4}{4x+4}=\dfrac{4}{5}\\\\5(3x+4)=4(4x+4)\\\\15x+20=16x+16\\\\20-16=16x-15x\\\\x=4\)

Raju's present age is 3(4) = 12 years

Ravi's present age is 4(4) = 16 years

The statistical technique used to predict the outcome of a variable of interest based on the value of a categorical variable is called logistic regression.

Logistic regression is a commonly used method when the dependent variable is binary or categorical. It allows us to estimate the probability of an event occurring based on one or more independent variables. The dependent variable, also known as the outcome or response variable, typically takes on two values (e.g., success/failure, yes/no).

To perform logistic regression, we use a mathematical function called the logistic function or sigmoid function, which maps any real-valued number to a value between 0 and 1. The logistic function is defined as:

P(Y=1) = 1 / (1 + e^-(β₀ + β₁X₁ + β₂X₂ + ... + βₖXₖ))

Where:

- P(Y=1) represents the probability of the event occurring.

- β₀, β₁, β₂, ..., βₖ are the coefficients to be estimated.

- X₁, X₂, ..., Xₖ are the independent variables.

To estimate the coefficients, various techniques such as maximum likelihood estimation or gradient descent can be used.

Logistic regression is a powerful statistical technique used to predict the outcome of a variable of interest based on the value of a categorical variable. By estimating the probabilities using the logistic function, we can assess the relationship between the independent variables and the likelihood of an event occurring. Logistic regression provides insights into the impact and significance of the categorical variable on the outcome, enabling prediction and inference in a wide range of fields such as medicine, marketing, and social sciences.

Step-by-step explanation:

using formula

270 degree/360 degree*pie*(r)^2

the sum of the terms of the series 36, 24, 16..., we can use the formula for the sum of an infinite geometric series is  is  -36,The limiting sum of a series is 36. If a = 8, we can find the value of r using the formula for the sum of an infinite geometric series is 7 / 9 and the total distance the ball falls is 16 meters.

Given a=−4 and r=2 in a geometric sequence, we can find the values of T3, T8, and Tn by using the formula for the nth term of a geometric sequence:

\(Tn = a * r^(n-1)\)

To find T3:
T3 = -4 * 2^(3-1)
T3 = -4 * 2^2
T3 = -4 * 4
T3 = -16

To find T8:
T8 = -4 * 2^(8-1)
T8 = -4 * 2^7
T8 = -4 * 128
T8 = -512

To find Tn, we need to know the value of n. Please provide the value of n to calculate Tn.

Now, let's move on to the series -3, 15, -75...

To find the common ratio (r), we can divide any term by its previous term. Let's use the second and first terms:

r = 15 / (-3)
r = -5

To find the first term (a), we can use the second term and the common ratio:

-3 = a * (-5)
a = -3 / (-5)
a = 3/5

Now, let's find the 11th term of the sequence:

T11 = a * r^(11-1)
T11 = (3/5) * (-5)^10
T11 = (3/5) * 9765625
T11 = 5859375/5
T11 = 1171875

Moving on to the next question:

1. To find the sum of the terms of the series 36, 24, 16..., we can use the formula for the sum of an infinite geometric series:

Sum = a / (1 - r)

Since this is an infinite series and the common ratio (r) is less than 1 in absolute value, the sum is finite. So, we can find the sum using the given values:

Sum = 36 / (1 - 2)
Sum = 36 / (-1)
Sum = -36

2. The limiting sum of a series is 36. If a = 8, we can find the value of r using the formula for the sum of an infinite geometric series:

Sum = a / (1 - r)

Substituting the given values:

36 = 8 / (1 - r)

Solving for r:

36(1 - r) = 8
36 - 36r = 8
36r = 36 - 8
36r = 28
r = 28 / 36
r = 7 / 9

3. A ball is dropped from 4 m and bounces back to 3/4 of its previous height. If it continues to bounce until it comes to rest, we need to find the total distance the ball falls.

The first fall from 4 m is straightforward, so the distance fallen is 4 m. For each subsequent bounce, the ball reaches 3/4 of its previous height, so the distance fallen decreases by a factor of 3/4 each time.

The total distance fallen can be calculated using the formula for the sum of an infinite geometric series:

Distance = a / (1 - r)

Substituting the given values:

Distance = 4 / (1 - 3/4)

Simplifying:

Distance = 4 / (1/4)
Distance = 4 * 4
Distance = 16 m

Therefore, the total distance the ball falls is 16 meters.

40V

Step-by-step explanation:

If the peak value of a sine wave is 80 vac. The peak-to-peak value of this waveform is: D. 160V.

The difference between a sine wave's positive and negative peaks is known as the sine wave's peak-to-peak value. The negative peak value, which has the same magnitude but the opposite sign as the positive peak value (80V), will be expressed as -80V.

So,  

Peak-to-peak value is:

Peak-to-peak value = Positive peak value - Negative peak value

Peak-to-peak value = 80V - (-80V)

Peak-to-peak value = 80V + 80V

Peak-to-peak value = 160V
