Textbook Question
Chapter 10.2, Problem 8P
For Problems 5–16, please provide the following information.
- (a) What is the level of significance? State the null and alternate hypotheses.
- (b) Find the value of the chi-square statistic for the sample. Are all the expected frequencies greater than 5? What sampling distribution will you use? What are the degrees of freedom?
- (c) Find or estimate the P-value of the sample test statistic.
- (d) Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis that the population fits the specified distribution of categories?
- (e) Interpret your conclusion in the context of the application.
Ecology: Deer The types of browse favored by deer are shown in the following table (The Mule Deer of Mesa Verde National Park, edited by Mierau and Schmidt). Using binoculars, volunteers observed the feeding habits of a random sample of 320 deer.
Use a 5% level of significance to test the claim that the natural distribution of browse fits the deer feeding pattern.

- As a project for her statistics class, a college student is interested in knowing what proportion of students at her college recycle aluminum cans. (a)The student would like her sample proportion to be within 0.04 of the true population proportion p. Can she make this happen? How? Or why not? (b)The student instead decides to make sure that 95% of all possible samples would have a sample proportion that is within 0.04 (Margin of Error) of the true population proportion. What does this mean the standard error must be? You can use the 68-95-99.7 Rule. (c)Assuming p = 0.5, how big should her sample size be?
