Chapter 2, Problem 2.6P
SW A local youth service agency has begun a sex education program for teenage girls who have been referred by the juvenile courts. The girls were given a 20-item test for general knowledge about sex, contraception, and anatomy and physiology upon admission to the program and again after completion of the program. The score of the first 15 girls to complete the program are as follows.
| Case | Pretest | Posttest | Case | Pretest | Posttest |

A quality characteristic of a product is normally distributed with mean μ and standard deviation σ = 1. Speci-
fications on the characteristic are 6≤x≤8. A unit that falls within specifications on this quality characteristic
results in a profit of Co. However, if x 8, the profit is -C2. Find the value
ofμ that maximizes the expected profit.
A) The output voltage of a power supply is normally distributed with mean 5 V and standard deviation 0.02 V. If
the lower and upper specifications for voltage are 4.95 V and 5.05 V, respectively, what is the probability that a
power supply selected at random conform to the specifications on voltage?
B)
Continuation of A. Reconsider the power supply manufacturing process in A. Suppose
We wanted to improve the process. Can shifting the mean reduce the number of nonconforming units produced?
How much would the process variability need to be reduced in order to have all but one out of 1000 units conform
to the specifications?

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?
