Q3. Management training programs are often instituted to teach supervisory skills and thereby increase productivity. Suppose a company psychologist administers a set of examinations to each of 10 super- visors before such a training program begins and then administers similar examinations at the end of the program. The examinations are designed to measure supervisory skills, with higher scores indicating increased skill. The results of the tests are shown below: Supervisor Pre-Test Post-Test 63 78 I 2 93 92 3 84 91 4 72 80 5 65 69 72 85 7 91 99 8 84 82 9 71 81 10 80 87 Do the data provide evidence that the training program is effective in increasing supervisory skills, as measured by the examination scores? Set up the appropriate hypotheses and test them at 5% significance level. State the assumptions made.
Show calculations or explanation for each question. a) A regression analysis between sales (in $1000) and advertising (in $100) resulted inthe following least squares line: y^=75+6x. This implies that if advertising is $800, thenthe predicted amount of sales (in dollars) is:a. $4875b. $123,000c. $487,500d. $12,300 b) The residual is defined as the difference between:a. the actual value of y and the estimated value of yb. the actual value of x and the estimated value of xc. the actual value of y and the estimated value of xd. the actual value of x and the estimated value of y c) In the simple linear regression model, the slope represents the:a. value of y when x = 0.b. average change in y per unit change in x.c. value of x when y = 0.d. average change in x per unit change in y

New Situation: Many meteorologists track named storms, particularly those that have the potential to make landfall; some meteorologists are more successful in predicting the track of the storm than others. Suppose all currently employed meteorologists are identified as either being employed by the U.S. National Weather Service, employed by a local television station within the United States, or employed in a country other than the United States. In this scenario, what is the population of interest?
