A researcher computed 90%, 95%, 98% and 99% confidence intervals for a population mean. However, he forgot to record which interval was which, and he cannot find the sample data to allow him to recreate the intervals from scratch. He now needs only the 99% confidence interval. Which one is it?        a-(37.9, 42.1)         b-(38.4, 41.6)         c-(38.1, 41.9)         d-(38.7, 41.3)
