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 . 2 Question 3: (a) la tis data dscrete or contrsous? O Discrete O Cortiruoun ®) Draw a histogram of he data and describe is shape. Choose the histogram below tat comecty depicts the given data O. 612546 Nuber 612545 Nuberf Nuer of D Numter D Describe the shape of the distribution. Choose the comect answer below. OA The distribution is skewed left. OB. The distribution is skewed right. O. The distribution is symmetric. (e) Based on the shape of the histogram, do you expect the mean to be more than, equal to, or less than the median? OA The mean should be substantialy smaller than the median. OB. The mean should be substantialy larger than the median. OC. The mean should be roughly equal to the median. (4) Compute the mean and median. What does this tell you? The mean isO (Type an integer or decimal rounded to two decimal places as needed.) The medan is (Type an integer or decimal rounded to two decimal places as needed.) What do the computed mean and median tell you Fin the blanks below. (Use a 25% aference as the oriterion for a substantiar diference between the mean and median) because the mean The prediction was e median in tis datrbuton. (0) Determine the mode. The mode isO (Type an integer or decimal rounded to two decimal places as needed.) M Do you believe that the survey sufers from bias? If so, what type and why? OA Yes, the survey sufers from sampling bias because the number of male and female students surveyed was not the same OB. 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. Yes, he survey suffers from response bias because it would be dificut to achieve truetl responses to this type of question unless the identity of the respondents is anonymous
