Question 1203005
mean is 197.5
sandard deviation is 8.9
proability of individual distance greater than 210.90 is equal to .0661.


if sample size is 15, then standard error = 8.9 / sqrt(15) = 2.29797
probability of getting the mean of the sample to be greaer than 196.2 is equal to .71422


the normal distribution can be used in part b, even though the sample size is less than 30, because the population is normally distributed.


here's what it looks like with an online calculator.
