Question 1074944
The mean of a sampling distribution is the mean of the population from which it was taken.  mean=64
the sd of a sampling distribution is the sd of the population divided by the square root (n)
This would be 18/sqrt(36)=3.  The sampling distribution is N~n=36 (64,3)
The probability p<62.6 is a z
z=(x bar-mean)/s/sqrt (n)
z<(62.6-64)/3
z<-1.4/3
z< -0.467.
p=0.3202
