A group of students in a math class were surveyed and asked: “How many hours each week do you study your math?” The following data represent the responses: 10, 1, 5, 5, 6, 3, 7, 3, 1, 6, 1, 9, 2, 4, 3, 2, 3, 2, 1, 3, 8, 2, 1. The standard deviation is 3. a) Construct a dot plot (on graph paper). b) Is this a normal distribution, or is the curve left skewed or right skewed?

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…
