Question 444133: Are the following statements a valid pair of null and alternative hypothesis?
Ho: U> 5 and Ha: u<17?
Is the following a valid null statement?
Ho : 13=11?
3.) Assume that a 95% confidence interval for the mean is (13.0, 15.0). What is the result of a hypothesis test of Ho u =1.0 at a (alpha) = 0.05?

Are the following statements a valid pair of null and alternative hypothesis?
Ho: U> 5 and Ha: u<17?
