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 less than 11 years. A survey of 77 companies reported The Wall Street Journal found a sample mean tenure of 9.8 years for CEOS with a standard deviation of 5 years (The Wall Street Journal, January 2, 2007). 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 0.001. Your hypotheses are: Ho : u > 11 H1:µ < 11 What is the test statistic for this sample? (Report answer accurate to 3 decimal places.) What is the p-value for this sample? (Report answer accurate to 4 decimal places.) This test statistic leads to a decision to O reject the null accept the null fail to reject the null As such, the final conclusion is that

What is the test statistic for this sample?
(Report answer accurate to 3 decimal
places.)
What is the p-value for this sample?
(Report answer accurate to 4 decimal
places.)
This test statistic leads to a decision to

As such, the final conclusion is that
there is sufficient evidence to conclude that the
population mean tenure for CEOS is equal to 11.
there is not sufficient evidence to conclude that
the population mean tenure for CEOS is equal to
