You are conducting a study to see if the typical doctor's salary (in thousands of dollars) is significantly different from 98. Your sample data (n=8) produce the test statistic t=-1.23. Find the p-value accurate to 4 decimal places. Test the claim that the mean GPA of night students is significantly different than 3 at the 0.02 significancelevel.The null and alternative hypothesis would be:Ο Η : μ = 3H : μ < 3O Ho: p = 0.75H₁: p < 0.75Ο Ηo : μ = 3H₁:μ ‡3Ho: p= 0.75H₁ :p>0.75O Ho: p = 0.75H₁: p/ 0.75Ο Η : μ = 3Η : μ > 3Based on a sample of 40 people, the sample mean GPA was 2.99 with a standard deviation of 0.03The test statistic isThe positive critical value isBased on this weO fail to reject the null hypothesisOrainhocic(to 3 decimals)(to 3 decimals) A shareholders' group is lodging a protest against your company. The shareholders group claimed that themean tenure for a chief exective office (CEO) was less than 10 years. A survey of 55 companies reported inThe Wall Street Journal found a sample mean tenure of 8.7 years for CEOs with a standard deviation of 4.2years (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 madeby the group, at a significance level of 0.002. Your hypotheses are:Ho : μ > 10H₁ : µ< 10What 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 toO reject the nullaccept the nullO fail to reject the nullAs such, the final conclusion is thatO there is sufficient evidence to conclude that the population mean tenure for CEOs is equal to 10.O there is not sufficient evidence to conclude that the population mean tenure for CEOs is equal to 10.O there is sufficient evidence to conclude that the population mean tenure for CEOs is less than 10.O there is not sufficient evidence to conclude that the population mean tenure for CEOs is less than
