Prоblem 1: Winter Vаriаbility A meteоrоlogist clаims that winter temperature swings have become more variable than usual. Historically, the standard deviation of daily winter temperatures is 4°F. A random sample of 20 winter days produced a sample standard deviation of 6°F. a) Test to see whether he is correct at a 5% significance level. b) Use the data to construct a 95% confidence interval around the sample standard deviation.
