1. A social psychologist surveyed 15 college students about the total number of phone calls they make during the week. The following scores were reported: 5, 1, 1, 0, 1, 1, 1, 4, 2, 1, 1, 2, 2, 4, and 2. a. What is the variable and scale of measurement for the above scenario? b. Make a frequency table for the above scores. c. Compute ALL measures of central tendency and variability for the above scores. d. Compute the z-scores for the above raw scores. Show ALL calculations. e. For the student with a raw score of 2, what does their z-score tell you? f. What visual representation would be appropriate for the above data and why?

Based on a study on midterm grades of 2000 students, a college professor found that the five-number summary is 10, 28, 55, 72, and 80, respectively. The total points for the exam are out of 100 points. The professor also found that the average midterm grade is 60 with a standard deviation of 10. Use the above information to answer 1a to 1d. 1a. Approximately how many students scored above 60? (1 pt) A) Between 0 and 500 students B) Between 500 and 1000 students C) Between 1000 and 1500 students D) Between 1500 and 2000 students E) Exactly 1000. 1b. Which of the following ranges contains the most students? (1 pt) A) 0 to 20 B) 20 to 28 C) 28 to 55 D) 55 to 70 E) 70 to 80 1c. Which of the following describes the shape of the distribution? (1 pt) A) Skew to the right because the mean is greater than the median. B) Skew to the right because the mean is less than the median. C) Skew to the left because the mean is greater than the median. D) Skew to the left because the mean is less than the median. 1d. Suppose Helen scored 25 points on the midterm. We can conclude that: (1 pt) A) Her grade is the 3rd quartile of the group. B) Exactly 25% of the students are doing better than Helen. C) Her grade is the 1st quartile of the group. D) Her grade is the 2nd quartile of the group. E) None of the above.

1. A question on a student survey asks: In a typical week, how many times do you eat at a fast food restaurant? The following data was then collected: No. of times per week No. of students 5 or more 2 4 2 3 3 2 6 1 0 0 3 A. Find the mode (number of times per week) for this data. B. Find the median (number of times per week) for this data. C. Explain why you cannot compute the mean number of times per week using the data in the table. 2. A sample of n = 7 scores has a mean of 5. After one score is added to the sample, the new mean is found to be 7. What is the value of the new score? (Hint: compare the values for ∑X before and after the score is added.) 3. What does it mean for a sample to have a standard deviation of zero? Describe the scores in such a sample. 4. Explain what it means to say that the sample variance provides an unbiased estimate of the population variance. 5. (Using both Excel and SPSS) For the following scores: 3, 1, 1, 1 Find the mean. Find the variance (show your work). Find the standard deviation. 6. (Using both Excel and SPSS) For the following scores: 1, 0, 4, 1, 1, 5 Find the mean. Find the variance (show your work). Find the standard deviation.

Lecturers at a university intend to see the effect of stress relief strategies such as deep breathing and relaxation techniques to the student performance in the final exam. For this reason, they assigned students of the same year in two different cohorts. More precisely, students in Cohort 1 did not do any relaxation techniques before the exam, while students in Cohort 2 performed a full range of the relaxation techniques approved by the British Psychological Society. The average mark of a random sample of 17 students from Cohort 1 was 61, with a standard deviation of 17, while the average mark of a random sample of 11 students from Cohort 2 was 67 with a standard deviation of 19. (a) Test whether the variances of marks for the two cohorts are the same at the 5% significance level. [7] (b) Test the hypothesis that the average mark in the exam for Cohort 1 students is the same as that for students of Cohort 2 at the 5% significance level. For this test, what is the p-value? [9] (c) What does the p-value that you calculated in (b) indicate about the null hypothesis? [2] (d) Calculate a 95% confidence interval for the difference in average marks in the exam for the two cohorts of students. Explain the meaning of the 95% confidence interval that you have calculated
