Chapter 12: Q.16 (page 521)

Hospitals. Refer to Problem 15 .

a. Obtain the conditional distribution of control type within each facility type.

b. Does an association exist between facility type and control type? Explain your answer.

c. Find the marginal distribution of control type.

a. Identify the populations under consideration.

b. Identify the variable under consideration.

c. At the 5% significance level, do the data provide sufficient evidence to conclude that people residing in the three types of residence are nonhomogeneous with respect to income level?

Short Answer

Expert verified

The over all shapes of the two sample distributions should be similar to that of the population distribution and hence to each other.

Step by step solution

01

Given Information

(a) The sample distribution would have resulted in a skewed form. This is because the distribution of a random sample selected from a population closely resembles the distribution of the entire population.

02

Definition

(b)

No, the two sample distribution would not be identical shapes, since the sample distributions vary from sample to sample.

03

Definition

(c)

Yes, the two sample distributions would have similar shape and that of left skewed shape. The over all shapes of the two sample distributions should be similar to that of the population distribution and hence to each other.

Consider a variable of several populations. Define the terms homogeneous and nonhomogeneous in this context.
Job Satisfaction. A CNN/USA TODAY poll conducted by Gallul asked a sample of employed Americans the following question: "Which do you enjoy more, the hours when you are on your job, or the hours when you are not on your job?" The responses to this question were cross-tabulated against several characteristics, among which were gender, age, type of community, educational attainment, income, and type of employer. The data are provided on the WeissStats site. In each of Exercises 12.87-12.92, use the technology of your choice to decide, at the5%significance level, whether an association exists between the specified pair of variables.

income and response

In each of Exercises 12.24-12.33, apply the chi-square goodness-of-fit test, using either the critical-value approach or theP-value approach, to perform the required hypothesis test.
Observing that the proportion of blue M&Ms in his bowl of candy appeared to be less than that of the other colors, R. Fricker, Jr., decided to compare the color distribution in randomly chosen bags of M&Ms to the theoretical distribution reported by M&M/MARS consumer affairs. Fricker published his findings in "The Mysterious Case of the Blue M&Ms" (Chance, Vol. 9(4), pp. 19-22). The following table gives the theoretical distribution.
For his study, Fricker bought three bags of M&Ms from local stores and counted the number of each color. The average number of each color in the three bags was distributed as follows.

Do the data provide sufficient evidence to conclude that the color distribution of M&Ms differs from that reported by M&M/MARS consumer affairs? Use α=0.05.

Suppose that you have bivariate data for an entire population.

a. How would you decide whether an association exists between the two variables under consideration?

b. Assuming that you make no calculation mistakes, could your conclusion be in error? Explain your answer.

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.
