Need help with my homework thank you  random sample of 6 fields of durum wheat has a mean yield of 45.5 bushels per acre and standard deviation of 7.43 bushels per acre. Determine the 80 % confidence interval for the true mean yield. Assume the population is approximately normal. Step 1: Find the critical value that should be used in constructing the confidence interval. Round  to three decimal places. Step 2 of 2: Construct the 80% confidence interval. Round  to one decimal place. I got 1.476 as my critical value and  41.0 and 49.9 as my confidence interval
