**Hypothesis Testing: Sampling Distribution Analysis****Instructions:**Determine whether the hypothesis test involves a sampling distribution of means that is a normal distribution, Student t distribution, or neither. Choose the correct distribution to be used to test each claim.**Problem 10:**a. **Claim:** - \(\mu = 107\) - **Sample Data:** - \(n = 17\) - \(\bar{x} = 101\) - \(s = 15.1\) - The sample data appear to come from a normally distributed population with unknown \(\mu\) and \(\sigma\). - **Distribution Choice:** [to be determined]b. **Claim:** - \(\mu = 981\) - **Sample Data:** - \(n = 23\) - \(\bar{x} = 912\) - \(s = 30\) - The sample data appear to come from a normally distributed population with \(\sigma = 30\).**Notes:**- For claim (a), the population standard deviation \(\sigma\) is unknown, so the Student t distribution is likely appropriate if the sample size is small (\(n < 30\)).- For claim (b), since the population standard deviation is given (\(\sigma = 30\)), the normal distribution could be used provided the sample size is large enough or the population is normally distributed.
