20. Solve the following problem:A panel of educators in a large urban community wanted to evaluate the effects ofeducational resources on student performance. They examined the relationshipbetween 12th-grade mean math SAT scores (Y) and the following independent vari-ables for a random sample of 25 high schools: X, = per pupil expenditure (in dollars);X = percentage of teachers with a master's degree or higher; and Xg = pupi-teacherratio. The sums of squares shown next can be used to summarize the key tesults fromthe regression of Y on X, Xp, and XySSY = 28,222.23 SSE = 2,248.23a. Determine the ANOVA table for the regression of Yon X, Xz, and Xg-b. Determine the R-value for the model in part (a). Based on this value, commenton whether the three educational resource variables appear to be associated withstudent performance.

The “promotions manager” of a large cosmetics manufacturer wanted to investigate user acceptance with a new formulation of their popular female facial cream. She organised for a sample of 5,000 users of the new formulation to be selected and sought their feedback on whether they were satisfied with its effects or not. Of the 2800 responses gained, 2,100 indicated that they were satisfied with the new formulation. i. State the name and the value of the statistic that is the best estimate for the proportion of all potential cream users that are satisfied

In 1908, William Gosset published the article "The probable Error of a Mean" under the pseudonym of "Student". He included the data listed below for two different types of corn seed that were used on ad jacent plots of land. The listed values are the yields of head corn in pounds per acre. Use a 0.10 significance level to test the claim that the mean difference in yield between the two types of seed is 0.

The city of Oakville has 60000 households. A social researcher from the University of Toronto collected a simple random sample of 100 households. Let the auxiliary variable x be the number of persons living in the household and y be the weekly spending for food. The researcher obtained the following sample statistics: 100 100 2 X; = 320 yi = 10000 E09 x? = 1250 100 E09 y? = 1100000 E00 x;y; = 36000 Ty = 150000 Sx = 1.5 Sy = 31.8 (a) Using the ratio estimation, estimate the mean weekly spending for food and place a bound on the error of estimation. You need to report the numerical values. Show all the steps. Circle the final answer. (b) Using the regression estimation, estimate the total weekly spending for food and place a bound on the error of estimation. You need to report the numerical values. USE MSE = 5200. Show all the steps. Circle the final answer.
