It is desired to estimate the proportion of cows conceiving at first service (breeding) in an artificial insemination (AI) program used on a particular farm. A random sample of 50 cow records is chosen; 30 of these 50 cows conceived at first service. Construct a 95% confidence interval for the true population proportion of cows conceiving at first service on this farm. You can assume that large-sample procedures are appropriate.
