Which test should be used one samples t test, independent samples t test or dependent samples t test. What do you set the hypothesis as

Question

Five people who were convicted of speeding were ordered by the court to attend a workshop. A special device put into their cars kept records of their speeds for two weeks before and after the workshop. The maximum speeds for each person during the two weeks before and the two weeks after the workshop are shown below. Using a two-tailed test, determine whether the workshop worked in reducing their speed.

Answer 1

There is data for these 5 people before and after the class.

You have two sets of data and since it is the same people in both groups this is a dependent test.

Answer 2

So will the hypothesis be Ho:md=0 and H1:md is not equal to 0

here are the scores for before 65,62,60,70,68 and after 58,55,56,66,60

Answer 3

what formulas do I use to start solving for t

Answer 4

use dependent samples t test. Set hypothesis so what formula will I use to solve

here are the scores for before 65,62,60,70,68 and after 58,55,56,66,60
hypothesis be Ho:md=0 and H1:md is not equal to 0
