See Answer →A study involves testing whether or not the amount of caffeine consumed affected memory. Fifteen volunteers took part in this study. They were given three types of drink (type A,B and C) containing different levels of caffeine (50 mg, 100 mg, and 150 mg, respectively). Volunteers were divided into three groups of five each and were assigned the drink groupwise. They were then given a memory test (In terms of number of words remembered from a list). The results are given in the following table:
| Group A (50 mg) | Group B (100 mg) | Group C (150 mg) |
| 7 | 11 | 14 |
| 8 | 14 | 12 |
| 10 | 14 | 10 |
| 12 | 12 | 16 |
| 7 | 10 | 13 |
At significance level of 5%, check whether the mean number of words remembered from the list by the participants belonging to the three groups are significantly different.

See Answer →The following table presents the number of hours a group of school students played video games during the weekends and the test scores attained by each of them in a test, the following Monday.
| Time (in hours) | Test score |
| 0 | 96 |
| 1 | 85 |
| 2 | 82 |
| 3 | 74 |
| 3 | 95 |
| 5 | 68 |
| 5 | 76 |
| 5 | 84 |
| 6 | 58 |
| 7 | 65 |
| 7 | 75 |
| 10 | 50 |
(a.) It is believed that a linear relationship exists between the time spent on playing video
games and test score attained. Find out the strength of this linear relationship.
(b.) Estimate the line of best fit in the scenario. Use this line to find the expected test
score for a student who plays video games for 9 hours.
