a) In 1920, the average age men got married for the first time
was 24.6 years. It is believed that young people are waiting longer
to get married. A recent study of 120 men found that the average

standard deviation of 5.2...

For the same significance level, which test is more stringent? In
other words, for which test does rejection of the null hypothesis
automatically imply rejection in the other test as well, but not
vice versa? Explain.
