For a population: a. with a standard deviation of σ= 15, how large a sample would be needed to have a standard error of 7 points? (This is a sample of people, so round to whole numbers.) b. with a standard deviation of σ = 32, how large a sample would be needed to have a standard error of 7 points? (This is a sample of people, so round to whole numbers.)
