Describe why. b) Use the information below to conduct a z-test using p=.05 as your alpha level. Make sure you complete all 5 steps and show your work/answers for every step. Sample Population: Mean = 3.13 Mean = 3.02 SD = 0.53 SD = 0.54 n = 86 c) Calculate a 95% confidence interval for the above sample.
