The number of people who dine at restaurants in Buffalo is normally distributed with a µ = 30 people and = 3 people. (Report both the z-scores and probability) What is the probability that the mean of 7 restaurants will have between 21 and 32 people dining there?        z1 =              z2 =              p(21 > M  > 32) =    What is the probability that the mean of 13 restaurants will have less than 21 people dining there?        z =         p(M < 21)=   Is the p=0 when the z score is extreme like -10 or 10?
