The breaking strength of a certain rivet used in a machine engine has a mean 5000 psi and standard deviation 400 psi. A random sample of 36 rivets is taken. Consider the distribution of the sample mean breaking strength. What sample n would be necessary in order to have to have a probability of 0.99 that the sample mean is between 4900 and 5100?
