Please help. I got several answers wrong and Im not sure how to correct them. Answers are below.

A shareholders' group is lodging a protest against your company. The shareholders group claimed that the mean tenure for a chief executive officer (CEO) was at least 11 years. A survey of 110 companies reported in The Wall Street Journal found a sample mean tenure of 9.1 years for CEOs with a standard deviation of s= 5.2 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 claim made by the group, at a significance level of =0.05. Your hypotheses are: Ho:=11 Ha:<11

What is the test statistic for this sample? test statistic = (Report answer accurate to 3 decimal places.) I put 2.832, which is wrong.

What is the p-value for this sample? p-value = (Report answer accurate to 4 decimal places.) I put 0.0028, which is wrong.
