Question
1. Find the standard deviation for the following data:57, 64, 43, 67, 49, 59, 44, 47, 61, 59 (answer in 2 dp)* A. 8.16 В. 8.18 C. 8.13 D. 8.20 2. A magazine printed a survey in its monthly issue and asked readers to fill it out and send it in. Over 1000 readers did so. This type of sample is called A. a cluster sample B. a self-selected sample C. stratified sample. D. simple random sample. 3. Which of the following statements is the most accurate description for the concept of standard deviation? * A. The average distance between a score and the mean. B. The square root of the total distance from the smallest score to the highest score. C. The total distance from the smallest score to the highest score. D. The squared average distance between all scores and the mean. 3. A randomized experiment was done by randomly assigning each participant either to walk for half an hour three times a week or to sit quietly reading a book for half an hour three times a week. At the end of a year the change in participants' blood pressure over the year was measured, and the change was compared for the two groups. "The two treatments in this study were: A. Walking or reading a book for half an hour three times a week and having blood pressure measures B. Walking or reading a book for half an hour three times a week and doing nothing. C. Having blood pressure measured at the beginning of the study and having blood pressure measured at the end of the day D. Walking for half an hour three times a week and reading a book for half an hour three times a week C. Option 2 4. Suppose the mean and standard deviation of the GPA's of all currently registered students at a college are mu = 2.70 and sigma = 0.50. The z-scores of the GPA's of two students, Antonio and Beatrice, are z = - 0.62 and z = 1.28 respectively. What is the GPA of Beatrice? * A. 2.39 В. 2.34 С. 3.34 D. 3.39
