- 10. A snowboarding competition site is using a new design for the parallel giant slalom. The designer of the slalom is investigating whether there is a difference in the mean times taken to complete a run for men and women competitors. As part of the investigation, independent random samples of men and women who will use the slalom run are selected and their times to complete a run are recorded. Which of the following is the appropriate inference procedure by which the designer can estimate the difference in the mean completion times for men and women? A A one-sample t-interval for a sample mean A one-sample t-interval for a population mean C A matched pairs t-interval for a mean difference A two-sample t-interval for a difference between population means E A two-sample t-interval for a difference between sample meanshow do i solve parts a, b, & c?The size of the p-value is influenced by the type of alternative hypothesis (either one or two-tailed).

- Do people in different political parties use similar modes of transportation? Researchers ask a group of people about how they get to work. They also group the people by their political party. They want to determine if the distribution of transportation is the same for democrats and republicans. The data are recorded in the contingency table below, and a chi-square Homogeneity Test at the 1% significance level is performed. Car Public Transit Walk Row Total Democrats 21 16 6 43 Republicans 8 25 16 49 Column Total 29 41 22 92 Select the correct null and alternative hypotheses for this test. Select all that apply: H0: The distribution of the two populations are the same. Ha: The distribution of the two populations are not the same. H0: The distribution of the two populations are not the same. Ha: The distribution of the two populations are the same.The hypothesis testing procedures for comparing means of INDEPENDENT samples would be appropriate for comparing Question 3 options: IQ scores of children attending a public elementary school as they progress from grade to grade. husbands’ and wives’ attitudes toward higher education. male and female problem solving skills (number of moves toward the correct solution) on a spatial puzzle task. software “usefulness” ratings by users who try both Software A and Software BConstruct a sample (with at least two differentvalues in the set) of 66 measurements whose median is smaller than the smallest measurement in the sample. If this is not possible, indicate "Cannot create sample".
