Suppose that you are testing the hypotheses Ho: μ=14 vs. HA: > 14. A sample of size 25 results in a sample mean of 14.5 and a sample standard deviation of 1.6. a) What is the standard error of the mean? b) What is the critical value of t for a 99% confidence interval? c) Construct a 99% confidence interval for μ. d) Based on the confidence interval, at a = 0.005 can you reject H₂? Explain. a) The standard error of the mean is (Type an integer or a decimal.)
