Work and explanation please! All steps.

To test H0: mu = 45 versus H1:mu a sample random sample of size n = 40 is obtained does population have to be normally distributed to test this hypothesis by using by using the methods present in this section ?why? If x= 48.3 and s= 8.5, compute the test statistic. Draw a t-distribution with the area that represents the P-value shaded. Determine and interpret the P-value. If the researcher decides to test this hypothesis at the alpha = 0.01 level of significance, will the researcher reject the null hypothesis? Why? (f, Construct a 99% confidence interval to test the hypothec
