I have tried 4 which was incorrect
as there are 3 values 79,80,82 that can be placed in group A ; while retaining top most 5 values also ; these 2 group can be interchanged ; hence total number of such arrangements =3*2 =6
( please revert)

Please answer question 3... I really don't know how to do it. For a comparison of two study guides for a mathematics course, 14 student volunteers were found. They were randomly assigned, 7 to study guide A, and 7 to study guide B. Following a two-day period of independent study, the students were examined on the material. The students received the following scores (out of 100): Study Guide A: 87 88 92 78 89 89 94 Study Guide B: 62...
For a comparison of two study guides for a mathematics course, 10 student volunteers were found. They were randomly assigned, 5 to study guide A, and 5 to study guide B. Following a two-day period of independent study, the students were examined on the material. The students received the following scores (out of 100): Study Guide A: 92 96 92 79 95 Study Guide B 68 74 81 72 78 Use a permutation test to test the null hypothesis that...

A study was carried out to assess the effect of a new medication in reducing blood pressure. In the trial, 59 subjects were enrolled, of which 30 were randomly allocated to receive a new treatment, while 29 received a control medication. After 20 weeks in the study, each subject's blood pressure, , was measured, leading to the following summary statistics: 9.63, 9.79, 1.41. With and representing the mean blood pressures in the treatment and control groups respectively, it is desired...

In Study Design 2, Super Sneaker Company drew at random two groups of 14 high school students from the Halifax school district database. After obtaining their shoe sizes, the company manufactured 14 pairs of shoes for group 1, each pair with both soles constructed from material A, and 14 pairs of shoes for group 2, each pair with both soles constructed from material B After 3 months, the amount of sole wear in each shoe was recorded in standardized units,...
A study was carried out to assess the effect of a new medication in reducing blood pressure. In the tria, 42 subjects were enrolled, of which 27 were randomly allocated to receive a new treatment, while 15 received a control medication. After 20 weeks in the study, each subject's blood pressure, X, was measured, leading to the following summary statistics: 12.46, rC-13.28, s 1.38. With T and representing the mean blood pressures in the treatment and control groups respectively, it...
