Answer the following questions using R studio
4. Test the Null hypothesis that the Dart scores from Group A is not
different from Group B and or Group A scores are greater than or
less than Group B.
Group A: 1,2,2,3,3,4,4,5,5,6
Group B: 1,2,4,5,5,5,6,6,7,9
5. The pre and post tests scores for a randomly selected group of
students before and after exposure to new teaching methods are
as follows:
Pretest: 10,5,8,6,4,5,5,8,7,6,10,5, 8,6,4,5,5,8,7,6
Posttest: 10,6,8,8,5,4,5,9,10,7, 8,5,4,5,9,10,7,10,6,8
Is there a significant difference in performance before compared to
after exposure to a different teaching method?
6. Results for blood glucose levels independently taken for the
same individuals before and after treatment with sucrose solution
to determine impacts of carbohydrates on blood sugar levels are
outlined below:
before : 200.1, 190.9, 192.7, 213, 241.4, 196.9, 172.2, 185.5, 205.2,
193.7
after : 392.9, 393.2, 345.1, 393, 434, 427.9, 422, 383.9, 392.3,
352.2
Select the appropriate test statistic to test the Null Hypothesis for
the that H0=H1.
7. Test the null hypothesis that Group 1 scores not Equal to Group
2 scores using the appropriate test statistics .
Group1= 19, 18, 9, 17, 8, 7, 16, 19, 20, 9, 11, 18
Group2= 16, 5, 15, 2, 14, 15, 4, 7, 15, 6, 7, 14
