Determine whether the hypothesis test involves a sampling distribution of means that is a normal distribution, Student tdistribution, or neither. Choose the correct distribution that will be use to test each claim.10) a. Claim: µ = 107. Sample data: n = 17, x = 101, s = 15.1. The sample data appear to comefrom a normally distributed population with unknown µ and o.10)b. Claim: u = 981. Sample data: n = 23, x = 912, s = 30. The sample data appear to comefrom a normally distributed population with o = 30.
