A shareholders' group is lodging a protest against your company. The shareholders group claimed that the mean tenure for a chief executive officer (CEO) was at least 9 years. A survey of 98 companies reported in The Wall Street Journal found a sample mean tenure of 8.7 years for CEOs with a standard deviation of $ s = 4.7 $ years (The Wall Street Journal, January 2, 2007). You don't know the population standard deviation but can assume it is normally distributed.You want to formulate and test a hypothesis that can be used to challenge the validity of the claim made by the group, at a significance level of $ \alpha = 0.001 $. Your hypotheses are:\[H_0: \mu \geq 9\]\[H_a: \mu < 9\] The image contains a set of questions typically found in a statistics worksheet or educational resource:1. **Question:** - "What is the test statistic for this sample?" - There is a blank box following the text, labeled as "test statistic =", indicating where a student should write their answer. - Instructions specify to "Report answer accurate to 3 decimal places."2. **Question:** - "What is the p-value for this sample?" - There is another blank box following the text, labeled as "p-value =", indicating where a student should write their answer. - Instructions specify to "Report answer accurate to 4 decimal places."This section is likely part of an exercise aimed at teaching students how to calculate and report test statistics and p-values in statistical analysis.

A psychologist has designed an index to measure the social perspectives of elementary school children. The index is based on ratings of a child’s responses to questions about a set of photographs showing different social situations. The following are the indices measured on a random sample of 16 children attending elementary school in a particular district. 48, 75, 69, 58, 60, 68, 59, 66, 71, 52, 49, 60, 54, 55, 70, 57 For the data the mean index is 60.69 and the standard deviation is 8.26. The confidence interval is 95%, with a level of significance of 0.05. Perform a statistical test to determine if the population mean index is greater than 50. a) Name of hypothesis test: b) H0: c) HA: d) Test Statistic: e) Rejection region: f) Decision in the context of the problem:
2. Scores in the first and fourth (final) rounds for a sample of 20 golfers who competed in PGA tournaments are shown in the following table (Golfweek, February 14, 2009, and February 28, 2009). Suppose you would like to determine if the mean score for the first round of a PGA Tour event is significantly different than the mean score for the fourth and final round. Does the pressure of playing in the final round cause scores to go up? Or does the increased player concentration cause scores to come down?
