A population has a normal distribution with a mean
of 83.1 and a standard deviation of 12.6.
Assuming nN/≤0.05nN≤0.05, the probability, rounded to three
decimal places, that the sample mean of a sample of
size 17 elements selected from this populations will be
less than 80.1 is:
of 83.1 and a standard deviation of 12.6.
