A sample of size 35 is drawn from a population with a normal distribution, and the sample mean is calculated. If the mean of the population is 15 with a standard deviation of 2.1, what is the probability the sample mean will be larger than 14?
P ( z > 14 − 15 2.1 35 )
P ( z > 14 − 15 2.1 )
P ( z > 15 − 14 2.1 35 )
