A random sample of 25 observations taken from a population that is normally distributed produced a sample mean of 58.5 and a standard deviation of 7.5. Find the critical and observed values of t for each of the following tests of hypothesis using a = 0.01. a) Ho:μ = 55 Ha:μ> 55 b) Ho:μ = 55 Ha: μ # 55
