Chapter 14.6, Problem 39E
In exercise 12, the following data on x = average daily hotel room rate and y = amount spent on entertainment (The Wall street Journal, August 18, 2011) lead to the estimated regression equation ŷ = 17.49 + 1.0334x. For these data SSE = 1541.4.
| City | Room Rate ($) |
Entertainment ($) |
| Boston | 148 | 161 |
| Denver | 96 | 105 |
| Nashville | 91 | 101 |
| New Orleans | 110 | 142 |
| Phoenix | 90 | 100 |
| San Diego | 102 | 120 |
| San Francisco | 136 | 167 |
| San Jose | 90 | 140 |
| Tampa | 82 | 98 |
- a. Predict the amount spent on entertainment for a particular city that has a daily room rate of $89.
- b. Develop a 95% confidence interval for the
mean amount spent on entertainment for all cities that have a daily room rate of $89. - c. The average room rate in Chicago is $128. Develop a 95% prediction interval for the amount spent on entertainment in Chicago.

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?
