Question

Calculate the p value and intrepret it. I got p-value = 0.0568 ; for e). Is the correct answer C?

A recent news report asserted that on average each college student consumes 12.56 alcoholic drinks per week Au 12.56), and the population standard deviation is 3.88 (o 3.88). An investigator at UCM tried to determine whether UCM students drink a different amount compared to the general college student population. Data from a sample of 30 UCM students indicate a weekly consumption level of 11.21 drinks 11.21). Based on the given information, answer the following questions (a) (f).

Explanation / Answer

(e)

Data:    

n = 30   

= 12.56   

s = 3.88   

x-bar = 11.21   

Hypotheses:   

Ho: = 12.56   

Ha: 12.56   

Decision Rule:   

= 0.05   

Lower Critical z- score = -1.959963985

Upper Critical z- score = 1.959963985

Reject Ho if |z| > 1.959963985

Test Statistic:   

SE = s/n = 3.88/30 = 0.708387841

z = (x-bar - )/SE = (11.21 - 12.56)/0.708387841040015 = -1.905735703

p- value = 0.056684505   

(f) Option A
