The university wants to see if a campaign on the negative effects of alcohol consumption and binge drinking could change the amount of undergraduate drinking on campus. A campaign was launched and a sample of 30 students from the university were selected to compare to the campus wide statistics on alcohol consumption. Use the data provided to answer the following questions. The information you will need to conduct the appropriate statistics for the university is provided below.

Average alcoholic beverages consumed per week:

N = 15, X = 5.20, = 6.30, sx = 3.80

What is the appropriate statistical test for this study (z-test/t-test)?

What is the standard/estimated standard error of the mean? Round to two decimal points.

What is the z_obt/t_obt? Round to two decimal places.

If our criteria for this test is two tailed test with = .05, then what would we say is the result of our analysis (specifically referring to the hypotheses)?
