In 1995, Cook County, Illinois (1.4 million households), conducted a study to determine how far the head ofhousehold travels to work. A simple random sample of 2,518 households was chosen and the occupantswere interviewed. The survey found that the mean commuting time for the head of households was 42.6minutes and the standard deviation was 16.7 minutes. Does the study suggest that the true average com-mute time for Cook County, IL in 1995 exceeds 42 minutes?1 2.1. Set up the hypotheses.1 2.2. Test your hypotheses with the significance level of a= 0.05 (5%).

N=2518 Mean =42.6 Standard deviation =16.7 Average =42 We have to test hypothesis.

3. Use the following information about the heights measured in feet of a sample of 40 Ponderosa Pine trees and 40 Eastern White Pine trees. Ponderosa Pine Trees: Mean of 77.5 ft with a standard deviation of 11.55 ft Eastern White Pine Trees: Mean of 67.25 ft with a standard deviation of 10.33 ft Is it more unusual for a Ponderosa Pine tree to have a height of 71 ft or an Eastern White Pine tree to have a height of 71 ft relative to the data of each species of tree?

Suppose that the average gregariousness score for the entire U.S. population is 70. The head research psychologist at Somerville University is interested in determining whether or not the university psychology students are statistically significantly more gregarious than the overall population. A random sample of 200 students from Somerville University shows a mean of 75 on the gregarious test with a sample standard deviation of 20. a. State the research hypothesis. b. State the null hypothesis. c. Identify the test statistic and provide the formula.
A study analyzed the sustainability behaviors of CPA corporations. The level of support for corporate sustainability (measured on a quantitative scale ranging from 0 to 160 points) was obtained for each in a sample of 984 senior managers at CPA firms. The CEO of a CPA firm claims that the true mean level of support for sustainability is 66. Complete parts a through e. What is a Type II error in this problem? A. A Type II error would be to conclude that the true mean level of support for sustainability is 66 when, in fact, the mean is not equal to 66. B. A Type II error would be to conclude that the sample mean level of support for sustainability is less than 66 when, in fact, the sample mean is greater than 66. C. A Type II error would be to conclude that the true mean level of support for sustainability is not 66 when, in fact, the mean is equal to 66. D. A Type II error would be to conclude that the sample mean level of support for…

The asking price for homes on the real estate market in Baltimore has a mean value of $286,455 and a standard deviation of $11,200. The mean and standard deviation in asking price for homes in Denver are $188,468 and $8,230, respectively. Recently, one home sold in each city where the asking price for each home was $193,000. Based on these data, which of the following conclusions can be made? A) The house in Baltimore is relatively farther from the mean than the house in Denver. B) The asking prices of homes in Denver is less variable than those in Baltimore. C) The distribution of asking prices in the two cities is bell-shaped. D) The two homes have approximately the same standardized values.
A hypothesis regarding the weight of newborn infants at a community hospital is that the mean is 7.1 pounds. A sample of seven infants is randomly selected and their weights at birth are recorded as 6.1, 8.1, 9.1, 10.1, 7.1, 11.1, and 12.1 pounds. What is the sample standard deviation?
Suppose the mean price for used cars is $10,198. A manager of a Kansas City used car dealership reviewed a sample of 50 recent used car sales at the dealership in an attempt to determine whether the population mean price for used cars at this particular dealership differed from the national mean.

The mean IQ of 200,000 current and past University of Manitoba students has been found to be 81.9. The standard deviation was found to be 13.1. The student enrollment at the University of Manitoba in 2016 was 29,987. The minimum IQ to be able to graduate from the University of Winnipeg has been found to be 104. Of the 29,987 students at the University of Manitoba in 2016, how many would be expected to be smart enough to graduate from the University of Winnipeg? Assume a Gaussian distribution.
