CEO Tenure. A shareholders’ group, in lodging a protest, claimed that the mean tenure for a chief executive office (CEO) was at least nine years. A survey of companies reported in The Wall Street Journal found a sample mean tenure of x̄ = 7.27 years for CEOs with a standard deviation of s = 6.38 years. 1 - Formulate hypotheses that can be used to challenge the validity of the claim made by the shareholders’ group. 2 - Assume 85 companies were included in the sample. What is the p-value for your hypothesis test? 3 - At α = .01, what is your conclusion?
