It is generally believed that there is a relationship between a college’s acceptance rate and its graduation rate. I wanted to know how strong this relationship is within the top universities in the country so I collected the graduation rate and acceptance rate data of a randomly selected sample of universities from all the top U.S. universities (with an acceptance rate at or below 30%). The data set is in Tab Q2 of the Excel data file. a.) Create a scatter plot between the two variables using Excel. Paste the plot here and format it into an APA-styled “figure” (see Assignment Guides for APA format).Be sure to submit the Excel file that you used to create the scatter plot. b) Calculate the mean and standard deviation for the two variables separately. c) Calculate the Z scores for all the scores of the two variables, separately.Tips: It may help to prevent error and to increase clarity if the process and/or the answers (z scores) are listed in a table format. d) Calculate…

Listed below are pulse rates (beats per minute) from samples of adult males and females. Find the mean and median for each of the two samples and then compare the two sets of results. Does there appear to be a difference? Male: Female: 86 71 54 84 57 95 53 89 53 63 59 72 68 85 87 90 91 88 70 92 77 63 82 53 91 88 94 82 86 64 Find the means. The mean for males is ☐ beats per minute and the mean for females is (Type integers or decimals rounded to one decimal place as needed.) beats per minute.

In a random sample of 250 women, 239 women said that they had less leisure time than they had 10 years ago. At a = 0.10, is there a difference in the proportions? There is enough evidence to support the claim that the proportions are different because the test value -2.77 is outside the noncritical region -1.65
