A company claims that the hold times for customer service averages at most 10 minutes. A random sample of 24 hold times has a mean of 11.2 minutes with a standard deviation of 5.2 minutes. Is there enough evidence to support the claim at α = 0.05? Assume the population is normally distributed.
Group of answer choices
Yes, since p of 0.135 is less than 0.05, reject the null. Claim is null, so is supported
No, since p of 0.135 is greater than 0.05, reject the null. Claim is null, so is not supported
No, since p of 0.135 is greater than 0.05, fail to reject the null. Claim is alternative, so is not supported
Yes, since p of 0.135 is greater than 0.05, fail to reject the null. Claim is null, so is supported
