Aman 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 (f). 0,1,0,0,0,0 1,0,0,0,0,4 1,5,1,1,0,4 1,0,0,1,0,1 2,0,1,1,,0,1,0 0,1,1,2,3,2 b) draw a histogram of the data and describe its shape. choose the histogram below that correctly depicts the given data. c. describe the shape of the distribution. choose the correct answer below. a. the distribution is skewed left. b. the distribution is symmetric. c. the distribution is skewed right. (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 roughly equal to the median. b. the mean should be substantially smaller than the median. c. the mean should be substantially larger than the median. (e) determine the mode. the mode is nothing . (type an integer or decimal rounded to two decimal places as needed.) (f) do you believe that the survey suffers from bias? if so, what type and why? a. yes, the survey suffers from sampling bias because the number of male and female students surveyed was not the same. b. yes, the survey suffers from sampling bias because the number of male and female students surveyed was the same. c. yes, the survey suffers from response bias because it would be difficult to achieve truthful responses to this type of question unless the identity of the respondents is anonymous. d. no, the survey does not suffer from bias because it was administered randomly and the question asked is in balanced form.

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
