Question
A man surveyed a sample of 36 high school students and asked, "How many days in the past week have you consumed an alcoholic beverage?" The results of the survey are shown to the right. Use these results to answer parts (a) through (). 4. 1 1 Question 3: 1 3 (a) Is this data discrete or continuous? Discrete O Continuous (b) Draw a histogram of the data and describe its shape. Choose the histogram below that correctly depicts the given data. OA. OB. Oc. OD. 20- 15- 10- 15- 10- Number of Drika Number of Drinks Number of Drinka Number of drinka Describe the shape of the distribution. Choose the correct answer below. O A. The distribution is skewed left. O B. The distribution is skewed right. OC. The distribution is symmetric. (c) Based on the shape of the histogram, do you expect the mean to be more than, equal to, or less than the median? A. The mean should be substantially smaller than the median. B. The mean should be substantially larger than the median. OC. The mean should be roughly equal to the median. (d) Compute the mean and median. What does this tell you? The mean is. (Type an integer or decimal rounded to two decimal places as needed.) The median is O. (Type an integer or decimal rounded to two decimal places as needed.) What do the computed mean and median tell you? Fill in the blanks below. (Use a 25% difference as the criterion for a "substantia" difference between the mean and median.) The prediction was the median in this distribution. because the mean (e) Determine the mode. The mode is O (Type an integer or decimal rounded to two decimal places as needed.) () Do you believe that the survey suffers from bias? If so, what type and why? O A. Yes, the survey suffers from sampling bias because the number of male and female students surveyed was not the same. O B. Yes, the survey suffers from sampling bias because the number of male and female students surveyed was the same. OC. No, the survey does not suffer from bias because it was administered randomly and the question asked is in balanced form. OD.
