tha======thank you so much

(Round your answer to two decimal places.) 12.71 X Compute the MSE for the five-week moving average forecasts. (Round your answer to two decimal places.) 9.12 XThe following data are product weights for the same items produced on two different production lines. Line 1 Line 2 13.6 13.7 13.8 14.1 14.0 14.2 13.9 14.0 13.4 14.6 13.2 13.5 13.3 14.4 13.6 14.8 12.9 14.5 14.4 14.3 15.0 14.9 Test for a difference between the product weights for the two lines. Use a = 0.05. State the null and alternative hypotheses. O Ho: Median for line 1 - Median for line 2 0 O Ho: The two populations of product weights are identical. Ha: The two populations of product weights are not identical. Find the value of the test statistic. W = Find the p-value. (Round your answer to four decimal places.) p-value = State your conclusion. O Reject Ho. There is sufficient evidence to conclude that there is a significant difference between the product weights for the two lines. Do not reject Ho. There is not sufficient evidence to conclude that there is a significant difference between the product weights for the two lines. O Reject H . There is not sufficient evidence to conclude that there is a significant difference between the product weights for the two lines. O Do not reject H . There is sufficient evidence to conclude that there is a significant difference between the product weights for the two lines
