Imagine that you are doing an exhaustive study on the children in all of the preschools in your school district. You are particularly interested in how much time children spend with parents on weekdays. You find that for this population of 2,431 children, the average number of minutes spent with parents on weekdays is μ = 223.17, with a standard deviation of σ = 148.75. You select a random sample of 25 children of preschool age in this same school district. In this sample, you find that the average number of minutes the children spend with parents on weekdays is M = 245.49, with a standard deviation of s = 163.63.
