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.

Bottled Water. A project exploring the bottled-water phenomenon and preference of water types was conducted by researchers M. Lunsford and A. Fink in the article "Water Taste Test Data" (Journal of Statistics Education, Vol. 18, No. 1). One hundred nine subjects participated in double-blind taste tests of three different bottled water brands (Fiji, Aquafina, and Sam's Choice) and tap water. Twelve people preferred the tap water, 27 Aquafino 44 Fiji, and 26 Sam's Choice. At the 5% significance level, do the data provide sufficient evidence to conclude that the four different water types are not equally likely in preference?

To decide whether two variables of a population are associated, we usually need to resort to inferential methods such as the chi-square independence test. Why?
