Aprofessor wanted to know whether there was a difference in students’ grade point averages (gpa) depending on whether they sit in the front half of the classroom versus the back half of the classroom. in a previous semester, a random sample of students was selected from the front of a classroom and another random sample was selected from the back of a classroom and the student’s current gpa was recorded. the data provided in statcrunch represent the gpas from each random sample. the file is called “gpa versus seating location.” at the 0.01 significance level, can the professor conclude from these data that the mean gpa for front sitters is higher than back sitters? assume all conditions for conducting inference are satisfied.

Ataxi company charges $2.25 for the first mile and then $0.20 per mile for each additional mile, or f = $2.25 + $0.20(m - 1) where f is the fare and m is the number of miles. if juan's taxi fare was $6.05, how many miles did he travel in the taxi? if juan's taxi fare was 7.65, how many miles did he travel in taxi
