A population has a mean muequals85 and a standard deviation sigma equals 24. find the mean and standard deviation of a sampling distribution of sample means with sample size nequals64.
The mean and standard deviation of the sample will be given by: standard deviation=σ/√n σ=24 n=64 thus standard deviation of the sample will be: 24/√64 =24/8 =3
mean the mean will be: μ+/-3 μ=85 thus the mean will be: 85+/-3 =82 or 88
