In an effort to improve the mathematical skills of 16 students, a teacher provides a weekly 1-hour tutoring session. A pre-test is given before the sessions and a post-test is given after. The results are shown here. Test the claim that there was an increase in the scores. at æ=0.05. You believe that the population is normally distributed, but you do not know the standard deviation. When calculating difference use Post- test minus Pre-test. pre-test post-test 64 54 94 103 58 62 76 73 60 55 78 78 43 41 77 73 99 89 69 69 40 36 88 91 83 82 76 85 98 106 58 52

Transcribed Image Text:In an effort to improve the mathematical skills of 16 students, a teacher provides a weekly 1-hour tutoring
session. A pre-test is given before the sessions and a post-test is given after. The results are shown here.
Test the claim that there was an increase in the scores. at a=0.05. You believe that the population is
normally distributed, but you do not know the standard deviation. When calculating difference use Post-
test minus Pre-test.

Transcribed Image Text:Which of the following are the correct hypotheses?
O Ho: µd 2 0
HA: Hd < 0(claim)
О Но: ра < 0
HA: Ha > 0(claim)
O Ho: µd =
HA: Hd + 0(claim)
Given that a is 0.05 the critical value is 1.753
The test statistic is:
(round to 3 places)
The p-value is:
(round to 3 places)
The decision can be made to:
O reject Ho
O do not reject Ho
The final conclusion is that:
