Using a two-sided abemaltive hypothesis, should you be able to reject the hypothesis that the population mean is 20 pounds using a significance level of 005? Amy or why not? The confidence interval is reported here: I am 95% confident the populabon mean is between 20. 1 and 22.3 pounds. b. Test the hypothesis that the populaion mean is not 20 Use a signiscance level of 0.05 C. Choose one of the following conclusions L We cannot reject a population mean ofl 20 pounds. E. We can reject a population mean of 20 pounds. i. The population mean is 21 2 pounds. a. Choose the correct answer below. OA. Do not reject the hypothesis, because the interval does not contain the proposed mean O B Reject the hypotesa, because the interval contains the proposed mean. C. Reject the hypothesis, because the interval does not contain the proposed mean. O D. There is insufficient information to determine if the hypothesis should be rejected.
