Reference no: EM13109970

The population of SAT scores forms the normal distribution with mean of µ=500 and standard deviation of o =100. If average SAT score is calculated for a sample of n=25 students,

A. Determine the probability that sample mean will be greater than M=510. In symbols, what is p(M>510)?
B. Determine the probability that sample mean will be greater than M=520. In symbols, what is p(M>520)?
C. Determine the probability that sample mean will be between M=510 and M=520? In symbols, determine p(510<M<520)?
