8.4 Observed Significance Levels: p-Values
Some researchers think that divorce is more likely when a couple marries at a young age. One researcher claims that the average divorced male was younger than 25 on the day of his wedding. A study of 33 divorced males shows their average age on the day of their wedding was 24.3 with a standard deviation of 2.5 years. At the 3% significance level use the p-value method to test the researcher’s claim.
