Chapter 14, Problem 1P
Define each of the following terms:
a. Factor
b. Level
c. Two-factor study
Expert Solution & Answer
To determine
Definitions of each of the following terms:
- Factor
- Level
- 2 factor study
Explanation of Solution
- Factor: The factor is an independent variable and is an explanatory variable that is manipulated by the experimenter. It designates the group being compared.
- Each factor has 2 more levels. Combination of different levels of factors make treatments.
- 2 factorstudies have 2 explanatory variables which the researcher is trying to study. Each factor may have different levels 2 or 3 each. That leads to 2 way Analysis of Variance. Each main effect,interaction between 2 factors,residual error and total variance can be studied in ANOVA and F tests are conducted to find its significance.

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?
