Suppose we know the standard deviation of the population is 3.7. We have a sample size of 625. We also have a sample mean of 46. We also have a population mean of 43. We want to test the hypothesis for the sample mean with 78% confidence level and do two-tailed test on the hypothesis. State the null and alternate hypothesis for the sample mean and then test the hypothesis to see if you will accept or reject the hypothesis. Please provide all calculations.
