Suppose we are interested in comparing the proportion of male students who smoke to the proportion of female students who smoke. We have a random sample of 150 students (60 males and 90 females) that includes two variables: Smoke = "yes" or "no" and Gender = "female (F)" or "male (M)". The two-way table below summarizes the results. Smoke = Yes Smoke = No Sample Size 60 90 Gender = M Gender = F Reference: 3-15-No Tech 9 9 51 81 Describe how to use the data to construct a bootstrap distribution. What value should be recorded for each of the bootstrap samples.

Morgan wants to test the speed for two different routes she can take to ride her bicycle home from work. Route A involves riding her bicycle on a busy road, and Route B involves riding her bicycle along a scenic trail. Assume that the population variances are not equal.Morgan collects some data, given below:Route A: xA=17.1 minutes, sA=4.6 minutes, nA=33 Route B: xB=15.8 minutes, sB=4.2 minutes, nB=39 _______________________________________________________________________________________ a. State the null and alternative hypothesis for the claim that Route A takes longer on average than Route B. b. We will use a/an (unpooled or pooled) t-test with _____ degrees of freedom. c. Calculate the standardized test statistic for the hypothesis test, rounded to 2 decimal places. Keep in mind that the formula for the denominator depends on whether the test is pooled or unpooled.

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…
