Chapter 12: Q. 12.8 (page 484)

For a 蠂2-curve with df=4, determine

a. 蠂0.0052

b.蠂0.012

Short Answer

Expert verified

Part a: The 蠂2value that has area 0.005with 4degrees of freedom is, 14.86which is illustrated graphically below,

Part b: The 蠂2value that has area 0.01with 4degrees of freedom is, 13.28which is illustrated graphically below,

Step by step solution

01

Part a Step 1. Given information

The number of degrees of freedom is,4.

02

Part a Step 2. To find the required χ2 value, we use tableV.

The number of degrees of freedom is, 4.So, first we go outside the columns. Then going across that row to the column labeled 蠂0.0052, we reach 14.86.

03

Part a Step 3. Let us illustrate our work graphically.

04

Part b Step 1. Given information

The number of degrees of freedom is,4.

05

Part b Step 2. To find the required χ2 value, we use table V.

The number of degrees of freedom is, 4.So, first we go outside the column. Then going across that row to the column labeled 蠂0.012, we reach13.28.

06

Part b Step 3. Let us illustrate our work graphically.

a. Find the conditional distribution of educational attainment with in each type of prison facility.

b. Does an association exist between educational attainment and of prison facility for prisoners? Explain your answer.

c. Determine the marginal distribution of educational attainment for prisoners.

d. Construct a segmented bar graph for the conditional distributions of educational attainment and marginal distribution of educational attainment that you obtained in parts (a) and (c), respectively. Interpret the graph in light of your answer to part (b).

categories.

Primary Heating Fuel. According to Current Housing Reports, published by the U.S. Census Bureau, the primary heating fuel for all occupied housing units is distributed as follows.

Suppose that you want to determine whether the distribution of primary heating fuel for occupied housing units built after 2010 differs from that of all occupied housing units. To decide, you take a random sample of housing units built after 2010 and obtain a frequency distribution of their primary heating fuel.

a. Identify the population and variable under consideration here.

b. For each of the following sample sizes, determine whether conducting a chi-square goodness-of-fit test is appropriate and explain

your answers: 200; 300; 400.

c. Strictly speaking, what is the smallest sample size for which conducting a chi-square goodness-of-fit test is appropriate?

In each of the given Exercises, we have given the number of possible values for two variables of a population. For each exercise, determine the maximum number of expected frequencies that can be less than 5 in order that Assumption 2 of Procedure 12.2 on page 506 to be satisfied. Note: The number of cells for a contingency table with m rows and n columns is m鈰卬.

12.70 five and three

In each of Exercises 12.18-12.23, we have provided a distribution and the observed frequencies of the values of a variable from a simple random sample of a population. In each case, use the chi-square goodness-of-fit test to decide, at the specified significance level, whether the distribution of the variable differs from the given distribution.

Distribution:0.5,0.3,0.2

Observed frequencies:147,115,88

Significance level=0.01

In Example 12.9 , we made the following statement: If no association exists between marital status and alcohol consumption, the proportion of married adults who abstain is the same as the proportion of all adults who abstain. Explain why that statement is true.
