A shareholders' group is lodging a protest against your company. The shareholders group claime that the mean tenure for a chief exective office (CEO) was at least 10 years. A survey of 84 companies reported in The Wall Street Journal found a sample mean tenure of 8 years for CEOS with a standard deviation of s = 5.6 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 clain made by the group, at a significance level of a = 0.10. Your hypotheses are: H.:µ > 10 Ha:µ < 10 What is the test statistic for this sample? test statistic = |(Report answer accurate to 3 decimal places.) What is the p-value for this sample? p-value = (Report answer accurate to 4 decimal places.)
