The table below contains the barley yields in bushels per acre grown at f 1 r7 six locations in 1932. Compute a 95% confidence interval for the '2 ' barley yields. Source: Immer, F.R., Hayes, H.D. and LeRoy Powers (1934) Statistical determination of barley varietal adaptation. Journal of the American Society for Agronomy. Fisher, R.A. (1947) The Design of Experiments. Directions: Click on the Data button shown below to display the data in a single column. Copy the data into a statistical software package and click the Data button a second time to hide it. Data a. Find the point estimate for the barley yield. Round your answer to 4 decimal places. H b. Determine the value of tc. Round your answer to 5 decimal places. U c. Compute the margin of error. Round your answer to 3 decimal places. H d. Construct the 95% confidence interval for barley yields. (Enter your answer as an open interval of the form (a,b) and round to 2 decimal places) e. Can you conclude that the barely yields were greater than 80 bushel per acre? 0 No, the entire confidence interval is below 80. 0 Yes, the entire confidence is above 80. O No conclusions can be drawn since the confidence interval contains 80
