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.
