The weights of four randomly and independently selected bags of potatoes labeled 20 pounds were found to be 21.8, 21.3, 20.4, and 21.4. Assume Normality. a. Using a two-sided alternative hypothesis, should you be able to reject the hypothesis that the population mean is 20 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 20.3 and 22.2 pounds. b. Test the hypothesis that the population mean is not 20. Use a significance level of 0.05. c. Choose one of the following conclusions: i. We cannot reject a population mean of 20 pounds. ii. We can reject a population mean of 20 pounds. iii. The population mean is 21.225 pounds. a. Choose the correct answer below. O A. There is insufficient information to determine if the hypothesis should be rejected. O B. Do not reject the hypothesis, because the interval contains the proposed mean. O C. Reject the hypothesis, because the interval does not contain the proposed mean. O D. Do not reject the hypothesis, because the interval does not contain the proposed mean. O E. Reject the hypothesis, because the interval contains the proposed mean
