A shareholders' group is lodging a protest against your company. The shareholders group claimed that themean tenure for a chief executive officer (CEO) was at least 10 years. A survey of 107 companiesreported in The Wall Street Journal found a sample mean tenure of 8.1 years for CEOS with a standarddeviation of s = 5.7 years (The Wall Street Journal, January 2, 2007). You don't know the populationstandard 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 madeby the group, at a significance level of a = 0.10. Your hypotheses are:H.:µ = 10Ha:µ < 10What 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.)

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 9 years.

In a school district, all sixth grade students take the same standardized test. The superintendant of the school district takes a random sample of 30 scores from all of the students who took the test. She sees that the mean score is 169 with a standard deviation of 7.0674. The superintendant wants to know if the standard deviation has changed this year. Previously, the population standard deviation was 13. Is there evidence that the standard deviation of test scores has decreased at the α=0.005 level? Assume the population is normally distributed. Step 4: Make a decision. Is it reject Null hypothesis or Fail to reject Null hypothesis? Step 5: What is the conclusion? Is there sufficient evidence or there is not sufficient evidence to show that the standard deviation of the test scores has decreased?
