A random sample of applicants for employment in 2020 to your company was administered two equivalent forms ("C" and "T") of an English uency test (in random order). The Form C test required that the applicant write as many words as possible beginning the letter "C" during a 20-second interval. The Form T test was the same as the Form C test except that the letter was changed to "T". This procedure was repeated using a random sample of applicants in 2021. Each applicant's "Form C score"I was calculated based on the number of "C" words correctly written; similarly, each applicant's "Form T score" was calculated based on the number of "T" words correctly written. Several questions concerning the underlyingpopulationt's) are at issue: 1. Is the 2021 average score on Form T greater than 7.0? 2. On average, do 2020 applicants do worse than 2021 applicants on Form C (assuming equal variances)? 3. On average, does the population of 2020- and 2021-applicants (combined! do better on one form than on the other? (If so, on which form do they do better?) 4. Can we be reasonably condent that more than 50% of the 2020 applicants achieve a Form T score greater than 5.0? 5. Can we be reasonably condent that a greater proportion of 2021 applicants than 2020 applicants achieve a Form C score greater than 4.5? 6. Can we be reasonably condent that, among the population of 2021 applicants, Form T scores are predictable from Form C scores? The data for this problem are contained in four data les: fluen2020c4xt, uen2020t.txt, fluen2021c.txt and uen2021t.txt. The "C" les contain scores on Form C; the "T" les contain scores on Form T; the "2020" les contain scores for 2020 applicants, and the I"2021" les contain scores for 2021 applicants. Any applicant contained on an "C" le will also be contained on the associated "T" le, and vice versa. Each le is formatted identically, with ID followed by Score
