milk production. Bauman et al. (Journal of Dairy Science, 1989) reported that 12 cows given bST produced an average of 28.0 kg/d of milk. Assume that the standart deviation of milk production is 2.25 kg/d. (a) Find a 99% confidence interval for the true mean milk production. Round your answers to two decimal places (e.g. 98.76). [26.33 SHST29.67 (b) If the farms want the confidence interval to be no wider than +1.20 kg/d, what level of confidence would they need to use? Express your answer in percent. Round your answer to the nearest integer (e.g. 98). confidence =T64.2
