2. A new pill is touted to improve the memory retention capability of teenagers aging 13 to 16 years old. To test this claim, twenty teenagers of the same age range are randomly picked to read the first two chapters of the book "Harry Potter and the Philosopher's Stone" after which they are asked to enumerate the number of verbs they remember from those chapters. Then they are given the new pill to be taken once daily for 7 days. At the end of 7 days, they are asked to read the same two chapters and enumerate the number of verbs they remember. The results are tabulated below: Number of verbs remembered Number of verbs remembered Тeen before taking the pill (X1) after taking the pill (X2) 1 6. 7 10 3 14 15 4 7 9. 8 12 4 10 7 5 7 8 3 9. 9 9 10 10 10 12 11 6. 12 8 9 13 4 10 14 8 8 15 9 13 16 6. 9. 17 11 13 18 7 6 19 20 8 At the 1% level of significance, what can you conclude?

For people who fill the long income tax form with illegal deductions, every 6 out of 9 know it is illegal, and the remaining 3 out of 9 did it incorrectly because they are unfamiliar with the tax regulations.

Among those who filled illegal deductions because of unfamiliarity, 100% deny knowledge of the error. If the filer filled out the form with illegal deductions and denies the knowledge of the error, what is the probability that the filer knows it's illegal?
