The weights of four randomly and independently selected bags of tomatoes labeled 5 pounds were found to be 5.2​, 5​, 5.2​, and 5. Assume Normality. a. Using a​ two-sided alternative​ hypothesis, should you be able to reject the hypothesis that the population mean is 5 pounds using a significance level of 0.05​? Why or why​ not? The confidence interval is reported​ here: I am 95​% confident the population mean is between 4.9 and 5.3 pounds. b. Now test the hypothesis that the population mean is not 5 pounds. Use a significance level of 0.05.
