A normally distributed population has a mean of
560
and a standard deviation of
60
.
a. Determine the probability that a random sample of size
25
selected from this population will have a sample mean less than
519
.
b. Determine the probability that a random sample of size
16
selected from the population will have a sample mean greater than or equal to
589
Although either technology or the standard normal distribution table could be used to find the probability, for this problem, use technology. Find the probability that
