Question:
Let x = age in years of a rural Quebec woman at the time of her first marriage. In the year 1941, the population variance of xwas approximately σ2 = 5.1. Suppose a recent study of age at first marriage for a random sample of 51 women in rural Quebec gave a sample variance s2 = 2.5. Use a 5% level of significance to test the claim that the current variance is less than 5.1. Find a 90% confidence interval for the population variance.
(a) What is the level of significance?
