Dairy cows at large commercial farms often receive
injections of bst (bovine somatotropin), a hormone used to
spur 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 standard deviation of milk
production is 2.25 kg/d.
(a) find a 99% confidence interval for the true mean milk
production.
(b) if the farms want the confidence interval to be no wider than
�1.25 kg/d, what level of confidence would they need to use?
