According to the National lnstitute on Alcohol Abuse and Alcoholism, 41% of college students nationwide engage in "binge drinking" behavior, having 5 or more drinks in one occasion during the past two weeks. A college president wonders if the proportion of students enrolled at her college that binge drink is actually lower than the national proportion.
ln a commissioned study, 348 students are selected randomly from a list of all students enrolled at the college. Of these, 132 admitted to having engaged in binge drinking.
At the 5% level of significance, is there enough evidence to conclude students enrolled at this college that binge drink is lower than the national proportion of students that binge drink?
2) Step 2: Collect the Data. This step means to find the summary data for the sample, and to assess normality, and to find the test statistic.
a) What is the sample proportion? Use 4 decimal places.
b) What is the standard deviation for this problem?
c) Are the normality assumptions met? Show or Explain fully.
d) What is the test statistic? If computing by hand do not used rounded values in your calculation, use all 8 decimals. Then round at the end of the calculation. Alternatively, obtain the test statistic from running the hypothesis test in the calculator. Use 4 decimal places.
