You are interested in purchasing a really good bull to breed your cows.  You look up the sale prices of a sample of 16 bulls that were sold in last year’s National Western Stock Show sale in Denver.  The average sale price was $10,000 with a standard deviation of $1,000.  You estimate the population mean for the sale prices of the bulls using a 95% confidence interval. What assumption must be met in order for the confidence interval that you constructed for the population mean for sale price of the bulls to be valid?

A population of rabbits has a mean weight of 10 lb and a standard deviation of the weights equal to 2 lb.  A rabbit breeder selects a large number of samples of 100 rabbits each, calculates the mean weight of the rabbits in each of these samples, and then graphs the sample means. The standard deviation of these sample means is expected to be equal to _______.

Assume that 16% of all pigs die between birth and weaning.  In a random sample of 300 births, let X be the number of pigs that die between birth and weaning.  Using the normal approximation to the binomial, find the approximate probability that the number of pigs in the sample of 300 that die between birth and weaning is greater than or equal to 50.
