Suppose that the population of the scores of all high school seniors who took the sat math (sat-m) test this year follows a normal distribution with standard deviation σ = 100.
you read a report that says, "on the basis of a simple random sample of 100 high school seniors that took the sat-m test this year, a confidence interval for μ is found to be 512.00 ± 25.76."
what was the confidence level used to calculate this confidence interval?
