Paint manufacture: Two methods are being considered to increase production of a paint manufacturing process. In a random sample of 52 days, the mean daily production using the first method was 645 tons with a standard deviation of 42 tons. In a random sample of 65 days, the mean daily production using the second method was 630 tons with a standard deviation of 44 tons. Part: 0/2 Part 1 of 2 (a) Construct a 80% confidence interval for the difference in mean daily production between the two methods. Let Hy denote the mean daily production using the first method. Use the table to find the critical value and round the answers to the nearest whole number. A 80% confidence interval for the difference in mean daily production between the two methods, in tons, is 4.7834-225.2166. X
