what is the critical value t* which satisfies the condition that the t distribution with 8 degrees of freedom has probability 0.10 to the right of t*?
Answers
To find the critical value t* for a t-distribution with 8 degrees of freedom, we need to use a t-table or a calculator with a t-distribution function. We want to find the value of t* such that the probability of getting a t-value greater than t* is 0.10 (or 10%).
Using a t-table, we can look for the row corresponding to 8 degrees of freedom and find the column that has a probability closest to 0.10. The closest probability in the table is 0.1002, which corresponds to a t-value of 1.859. Therefore, the critical value t* for a t-distribution with 8 degrees of freedom and a probability of 0.10 to the right of t* is approximately 1.859.
Alternatively, we can use a calculator with a t-distribution function to find the critical value. We can input the degrees of freedom (8) and the probability to the right of the critical value (0.10) into the calculator. The result is approximately 1.859.
In conclusion, the critical value t* for a t-distribution with 8 degrees of freedom and a probability of 0.10 to the right of t* is approximately 1.859.

Apex To construct the midpoint of a given line segment, fold the paper so that the given line segment lies on itself and:
Pls help pls A. the endpoints lie on each other.
B. is perpendicular to the papers edge. C. on the point. D. the fold is parrallel to the line.
Answers
The fold is on the point, meaning that the fold line passes through the midpoint of the given line segment.
The correct answer is option C:
To construct the midpoint of a given line segment, we need to fold the paper in such a way that the fold line satisfies the condition of being on the point.
Take a ruler and draw the given line segment on the paper, ensuring it is straight and accurate.
Identify the two endpoints of the line segment, and let's label them as A and B.
Fold the paper so that the two endpoints, A and B, coincide with each other.
This means that you align point A directly onto point B, creating a fold that merges the two endpoints together.
As you fold the paper, make sure to keep the rest of the line segment straight and flat against the paper.
This step ensures that the line segment lies on itself without any bends or twists.
Once the paper is fully folded, we will have a crease line running through the midpoint of the line segment.
This crease line is the fold line that represents the midpoint of the line segment.
By folding the paper in such a way that the endpoints coincide, you effectively bisect the line segment and create a fold line that passes through the midpoint.
This method allows you to construct the midpoint accurately without any measurements or calculation.
Therefore, the correct answer is option C: the fold is on the point, meaning that the fold line passes through the midpoint of the given line segment.

Two sides of a triangle are 7 cm and 4 cm. which measure could not be a length of the third side?
Answers
Third length of the triangle will be lies between 3cm < l < 11 cm if the two sides of the triangle are 7 cm and 4 cm.
Let the measure of third side of the triangle is ‘l’ cm
We know that the sum of two sides of a triangle is always greater than the measure of the third side.
We can say that,
l < 4 + 7
⇒ l < 11cm
It is also said that the measure of a side of a triangle is always greater than the difference of the other two sides of the triangle, concluding that
l > |7 - 4|
⇒ l > 3cm
From the above conditions, we can say that ‘l’ lies between 3 cm and 11 cm.

Answers
The probability of renting exactly three apartments in a week is approximately 0.2018 or 20.18%.
If the average number of units rented per week is 2.3 and the distribution is Poisson, then the parameter lambda is also equal to 2.3.
The probability of renting exactly three apartments in a week is given by the Poisson probability function:
\(P(X = 3) = (e^(-lambda) * lambda^x) / x!\)
Substituting the values, we get:
\(P(X = 3) = (e^(-2.3) * 2.3^3) / 3!\)
P(X = 3) = (0.09963 * 12.167) / 6
P(X = 3) = 0.2018
Therefore, the probability of renting exactly three apartments in a week is approximately 0.2018 or 20.18%.

1) A nutrician major separates 60 volunteers into the 55 who like Ovaltine and the 5 people who don't. IQ tests are given to the volunteers. She questions whether Ovaltine preference matters at all. Perhaps they have the same IQ on average with the same standard deviation. She wants to test if those who like Ovaltine have a higher IQ on average by assuming normality.
2) An engineering major wants to estimate the difference in tensile strength between oak wood beams and elm wood beams. She believes the standard deviations should be equivalent. She gathers 50 beams of each type and tests their tensile strength.
Answers
G. One sample t-test for a proportion.
The nutrition major wants to test if there is a difference in IQ between those who like Ovaltine and those who don't. Since she is comparing proportions, she should use a one-sample t-test for a proportion.E. Two sample t-test for means independent.
The engineering major wants to estimate the difference in tensile strength between two types of wood beams. Since she has two independent samples and wants to compare their means, she should use a two-sample t-test for means independent.A. In scenario 1, the nutrition major is interested in comparing the mean IQ scores of two groups: those who like Ovaltine and those who don't. Since the sample size of the group who don't like Ovaltine is small (n=5), it's not appropriate to use a z-test. Instead, a one-sample t-test for a mean can be used to compare the mean IQ scores of those who like Ovaltine to a hypothesized population mean (which could be the population mean IQ score, assuming that Ovaltine preference doesn't affect IQ).
B. In scenario 2, the engineering major is interested in comparing the means of two independent groups (oak wood beams and elm wood beams) with equivalent standard deviations. Since the sample sizes are both 50 and the standard deviation of the population is unknown, a two-sample t-test for means can be used to compare the means of the two groups.
C. In a matched pairs difference in means scenario, each subject in a sample is paired with another subject based on some characteristic that affects the outcome of the study (such as age, weight, or gender). In this scenario, the difference in scores between each pair of subjects is calculated, and a one-sample t-test can be used to determine whether the average difference between the two groups is statistically significant.
D. In a two-sample z-test for means scenario, the researcher is interested in comparing the means of two independent groups with known population variances. This type of test is rarely used in practice since population variances are usually unknown.
E. In a two-sample t-test for means independent scenario, the researcher is interested in comparing the means of two independent groups with unknown population variances. This is the most commonly used test for comparing the means of two independent groups.
F. In a one-sample z-test for a proportion scenario, the researcher is interested in testing whether a sample proportion is significantly different from a hypothesized population proportion.
G. In a one-sample t-test for a proportion scenario, the researcher is interested in testing whether a sample proportion is significantly different from a hypothesized population proportion when the sample size is small and/or the population variance is unknown.
H. In a two-sample z-test for the p1-p2 scenario, the researcher is interested in comparing two proportions in two independent groups with known population variances.

You want to develop a three-sigma X Chart. You know the mean of the
means is 20 and the average range is 5 based on several samples of
size 10. What is the LCL of the X Chart? Roun
Answers
To develop a three-sigma X Chart with a known mean of the means as 20 and an average range of 5, based on samples of size 10, the Lower Control Limit (LCL) can be calculated as 14.5.
The X Chart, also known as the individual or subgroup chart, is used to monitor the central tendency or average of a process. The control limits on an X Chart are typically set at three standard deviations above and below the mean.
To calculate the LCL of the X Chart, we need to subtract three times the standard deviation from the mean of the means. Since the average range (R-bar) is given as 5, we can estimate the standard deviation (sigma) using the formula sigma = R-bar / d2, where d2 is a constant value based on the sample size. For a sample size of 10, the value of d2 is approximately 2.704.
Now, we can calculate the standard deviation (sigma) as 5 / 2.704 ≈ 1.848. The LCL can be determined by subtracting three times the standard deviation from the mean of the means: LCL = 20 - (3 * 1.848) ≈ 14.5.

a 200-foot tall monument is located in the distance. from a window in a building, a person determines that the angle of elevation to the top of the monument is 19°, and that the angle of depression to the bottom of the tower is 6°. how far is the person from the monument? (round your answer to three decimal places.)
Answers
The person is approximately 579.710 feet away from the monument.To solve this problem, we can use trigonometric ratios. Let's denote the distance from the person to the monument as 'd'.
We can set up the following equations: tan(19°) = 200/d (angle of elevation); tan(6°) = 200/(d + h) (angle of depression). We know that the height of the monument is 200 feet. Now we can solve for 'd' by substituting the values and solving the equations simultaneously. Using a scientific calculator, we have: tan(19°) ≈ 0.345; tan(6°) ≈ 0.105.
From the first equation, we get: 0.345 = 200/d. Solving for 'd', we find: d ≈ 200/0.345 ≈ 579.710. Therefore, the person is approximately 579.710 feet away from the monument.
