A student at Tolland High School wondered if boys or girls at her school traveled a greater distance to college. The student randomly selected 50 boys and 50 girls and found the distance each boy and girl travels to college. 

What type of interval should the student use to compute the difference in the average distances between how far boys and girls from Tolland High School travel to college?

 

A) x= 5.5 s= 2.7 n= 20 df= 19
(3.97, 7.03)
Based on the sample, there's a 98% confidence level that the true mean of the length of the 20
selected words ranges from 3.97 to 7.03.
B) Since the p- value is too high we don't reject H. The sample doesn't provide enough evidence
that suggests that the average word length differs from the goal of the 6.5 letters.
