The number of credits being taken by a sample of 13 full-time college students are listed below. Find the mean, median, and mode of the data, if possible. If any measure cannot be found or does not represent the center of the data, explain why. 88 11 11 8 9 77777 7 10 TMV UIG TIHVUG.

Use a comma to separate answers as needed.) O B. The data set does not have a mode. Does (Do) the mode(s) represent the center of the data? O A. The mode(s) represent(s) the center. O B. The mode(s) does (do) not represent the center because it (one) is the largest data value. O C. The mode(s) does (do) not represent the center because it (one) is the smallest data value. O D. The mode(s) does (do) not represent the center because it (they) is (are) not a data value. O E. The data set does not have a mode.
1. Explain the difference between z-tests (which use categorical data), and t-tests (which use numerical data). 2. Conduct a t-test, both when given statistics, and when given data. 3. Conduct a t-test, 2-sample t-test, and paired t-test. 4. Differentiate between the five types of tests we have learned so far.

11. Doing homework A school newspaper article claims that 60% of the students at a large high school completed their assigned homework last week. Assume that this claim is true for the 2000 students at the school. a. Make a bar graph of the population distribution. b. Imagine one possible SRS of size 100 from this population. Sketch a bar graph of the distribution of sample data.
13. Dave likes to grow cucumbers, and each year he experiments with ways to improve his crop. This summer, he wants to determine whether the new fertilizer he has seen advertised will increase the mean number of cucumbers produced per plant. He uses the old fertilizer on 15 cucumber plants and the new fertilizer on the other 13 plants. Over the course of the growing season, he calculates a mean of 17.4 cucumbers per plant for the old fertilizer, with a standard deviation of 2.0 cucumbers. He calculates a mean of 21.6 cucumbers per plant for the new fertilizer, with a standard deviation of 2.7 cucumbers. You may assume that both samples came from populations that are approximately normal. Assume that the population variances are not equal. a. Determine the best point estimate for the true mean difference in cucumber production. Correct notation counts. b. Construct a 95% confidence interval for the true mean difference in cucumber production. For credit, your work must include a…
