A horse trainer teaches horses to jump by using two methods of
instruction. Horses being taught by method A have a lead horse that
accompanies each jump. Horses being taught by method B have no lead
horse. The table shows the number of training sessions required
before each horse performed the jumps properly.

Use a rank-sum test with a 10% level of significance to test the claim that there is no difference between the training sessions distributions. State the conclusion of the test and interpret your results with a 10% level of significance.
| a. |
Since the P-value is greater than the level of significance, the data are statistically significant. Based on this, we reject the null hypothesis. |
|
| b. |
Since the P-value is greater than the level of significance, the data are statistically significant. Based on this, we fail to reject the null hypothesis. |
|
| c. |
Since the P-value is less than the level of significance, the data are statistically significant. Based on this, we reject the null hypothesis. |
|
| d. |
Since the P-value is less than the level of significance, the data are statistically insignificant. Based on this, we fail to reject the null hypothesis. |
|
| e. |
Since the P-value is greater than the level of significance, the data are statistically insignificant. Based on this, we fail to reject the null hypothesis. |

Suppose that a MBA level stat course is taught using four
different methods of instruction: (1) 100% online; (2) a “half and
half” format where one week the class meets for a lecture, the next
week, material is posted online, etc.; (3) traditional weekly
lecture meetings plus supplementary material posted online; and (4)
traditional weekly lecture meeting with no use of the web.
Twenty students are surveyed from each course

Two sections of a class in statistics were taught by two
different methods. Students’ scores on a standardized test are
shown in Table 5.12 . Do the results present evidence of a
difference in the effectiveness of the two methods? (Use α
= 0.05.)
Class A: 74, 97, 79, 88, 78, 93, 76, 75, 82, 86, 100, 94
Class B: 78, 92, 94, 78, 71, 85, 70, 79, 76, 93, 82, 69, 84
Include R code.
