A shareholders’ group, in lodging a protest, claimed that the mean tenure for a chief executive officer (CEO) was at least 9.5 years. A survey of companies reported in The Wall Street Journal found a sample mean tenure of x̅ = 7.22 years for CEOs with a standard deviation of s = 6.32 (The Wall Street Journal, January 2, 2007). Assume 90 companies were included in the sample. What is the p-value for your hypothesis test?
