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 - 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 u is found to be 512.00 + 25.76." What was the confidence level used to calculate this confidence interval? A) 90% В) 95% С) 99% D) 99.9%
