Chapter 11.4, Problem 45E
a. An experiment was carried out to investigate the effects on audio sensitivity of varying resistance (A), two capacitances (B, C), and inductance of a coil (D) in part of a television circuit. If four blocks were used with four treatments per block and the defining effects for confounding were AB and CD, which treatments appeared in each block?
b. Suppose two replications of the experiment described in part (a) were performed, resulting in the accompanying data. Obtain the ANOVA table, and test all relevant hypotheses at level .01.

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?

15. How does the first measurement compare with the expected value?
16. How does the second measurement compare with the expected value?

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%.
