Expert Solution
Step 1
according to central limit theorem if sample size is large enough i.e. greater than 30 then sampling distribution of mean is approximately normally distributed with mean equal to population mean μ and standard error σ /√n.
So first of all we will calculate corresponding z score and then we shall find required probability as follows with the help of normal distribution table.
P(X<x) = p(Z<z)
