Question
Chapter 10, Problem 110UP
To determine
Explain the difference between one way ANOVA and two way ANOVA.
Expert Solution & Answer
Explanation of Solution
Difference between one way ANOVA and two way ANOVA:
- One way ANOVA is used to test the significant difference between more than 2 means, whereas two way ANOVA is used to test the relationship between two independent variables and one dependent variable.
- One way ANOVA consists of only one independent variable, whereas two way ANOVA consists of two independent variables.

4.96 The breaking strengths for 1-foot-square samples of a particular synthetic fabric are approximately normally distributed with a mean of 2,250 pounds per square inch (psi) and a standard deviation of 10.2 psi. Find the probability of selecting a 1-foot-square sample of material at random that on testing would have a breaking strength in excess of 2,265 psi.4.97 Refer to Exercise 4.96. Suppose that a new synthetic fabric has been developed that may have a different mean breaking strength. A random sample of 15 1-foot sections is obtained, and each section is tested for breaking strength. If we assume that the population standard deviation for the new fabric is identical to that for the old fabric, describe the sampling distribution forybased on random samples of 15 1-foot sections of new fabric
