A hypothesis test is performed to determine if the proportion of all six packs of seltzers sold in a particular grocery store ne
ar a college campus that are alcoholic exceeds 50%. A random sample of 152 customers that purchased seltzer is acquired (assume no customer purchases more than one six pack at time, alcoholic or not); the sample proportion of these purchases that are alcoholic is obtained. From this sample a test statistic of 2.60 is calculated, which has a corresponding P-value of 0.0047.Which of the following is true? a. None of these statements is true.
b. The probability that, in a random sample of 152 customers purchasing seltzers, more than 50% of those customers will have purchased alcoholic seltzer is 0.0047.
c. The probability the null hypothesis is true is 0.0047.
d. The probability that 50% of customers purchasing seltzers will be purchasing alcoholic seltzer on any given day is 0.0047.
e. The probability the null hypothesis is true is 1-0.0047 = 0.9953.
