Lecture Examples
Example 123: A sociologist claims that the average Hispanic teen male is engaging in intercourse before turning 17 years old. A 2008 study of 47 Hispanic males revealed that the mean age at which they had intercourse for the first time was 16.31 years old with a standard deviation of 1.78 years. Use a 0.01 significance level to test the sociologist’s claim that the mean age for Hispanic males to first engage in intercourse is less than 17 years old.
