A shareholders' group is lodging a protest against your company. The shareholders group claimed that the mean tenure for a chief exective office (CEO) was at least 8 years. A survey of 106 companies reported in The Wall Street Journal found a sample mean tenure of 6.1 years for CEOS with a standard deviation of s = 5.1 yeara (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 a = 0.10. Your hypotheses are: Ho:µ > 8 Haiu < 8 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.) The p-value is. O less than (or equal to) a Ogreater than a This test statistic leads to a decision to. Greject the nul: Oaccept the null O fail to reject the null
