**Educational Content: Hypothesis Testing on Child Booster Seat Safety****Scenario:**Assume that a simple random sample has been selected from a normally distributed population, and test the given claim. The goal is to identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim.**Objective:**A safety administration conducted crash tests of child booster seats for cars. The results are listed below, with measurements in hic (standard head injury condition units). The requirement is that the hic measurement should be less than 1000 hic. The significance level is 0.01.**Data:**- Measurements: 776, 636, 1213, 619, 557, 531**Task:**Determine if the sample is from a population with a mean less than 1000 hic. Do the results suggest that all child booster seats meet the specified requirement?**Hypotheses:**- (C) Null Hypothesis $ H_0: \mu = 1000 $ hic- Alternative Hypothesis $ H_1: \mu < 1000 $ hic**Identify the Test Statistic:**- The formula for the test statistic $ t $ is needed.- Instructions: Round to three decimal places as needed.*Explanation:*In the given problem, we aim to determine if the mean hic measurement for the booster seats is less than 1000 hic, indicating they pass the safety requirement. The setup involves performing a one-sample t-test with a specified significance level to draw conclusions based on the collected data.**Note:**- No graphs or diagrams are present in this content.

The coach of a very popular men’s basketball team claims that the average distance the fans travel to the campus to watch a game is 35 miles. The team members feel otherwise. A sample of 16 fans who travel to games was randomly selected and yielded a mean of M= 36 miles and s= 5 miles. Test the coach’s claim at the 5% (.05) level of significance. one-tailed or two-tailed test: State the hypotheses: df= tα or t value for the critical region = sM = t (test statistic)= Decision:
