- a. Develop an estimated regression equation with the amount of television advertising as the independent variable. Test for a significant relationship between television advertising and weekly gross revenue at the 0.05 level of significance. What is the interpretation of this relationship?
- b. How much of the variation in the sample values of weekly gross revenue does the model in part (a) explain?
- c. Develop an estimated regression equation with both television advertising and newspaper advertising as the independent variables. Test whether each of the regression parameters β0, β1, and β2 is equal to zero at a 0.05 level of significance. What are the correct interpretations of the estimated regression parameters? Are these interpretations reasonable?
- d. How much of the variation in the sample values of weekly gross revenue does the model in part (c) explain?
- e. Given the results in parts (a) and (c), what should your next step be? Explain.
- f. What are the managerial implications of these results?

Two measurements are made of some quantity. For the first measurement, the average
is 74.4528, the RMS error is 6.7441, and the uncertainty of the mean is 0.9264. For the
second one, the average is 76.8415, the standard deviation is 8.3348, and the uncertainty of
the mean is 1.1448. The expected value is exactly 75.
13. Express the first measurement in public notation.
14. Is there a significant difference between the two measurements?

In addition to the in-school milk supplement program, the nurse would like to increase the use of daily vitamin supplements for the children by visiting homes and educating about the merits of vitamins. She believes that currently, about 50% of families with school-age children give the children a daily megavitamin. She would like to increase this to 70%. She plans a two-group study, where one group serves as a control and the other group receives her visits. How many families should she expect to visit to have 80% power of detecting this difference? Assume that drop-out rate is 5%.
