A customer service phone line claims that the wait times before a call is answered by a service representative is less than 3.3 minutes. In a random sample of 62 calls, the average wait time before a representative answers is 3.26 minutes with a standard deviation of 0.14 minutes. Can the claim be supported at =0.08?
a. No, since the p-value (0.01) is less than alpha, reject the null. The claim is the alternative, so the claim is not supported
b. Yes, since the p-value (0.01) is less than alpha, reject the null. The claim is the alternative, so the claim is supported
c. Yes, since the p-value (0.99) is greater than alpha, reject the null. The claim is the alternative, so the claim is supported
d. No, since the p-value (0.99) is greater than alpha, reject the null. The claim is the alternative, so the claim is not supported
