Chapter 11: Q. 58 (page 758)

For these data, 蠂2=69.8with a P-value of approximately 0. Assuming that the researchers used a significance level of 0.05, which of the following is true?

a. A Type I error is possible.

b. A Type II error is possible.

c. Both a Type I and a Type II error are possible.

d. There is no chance of making a Type I or Type II error because the P-value is approximately 0.

e. There is no chance of making a Type I or Type II error because the calculations are correct.

Short Answer

Expert verified

Option a) is correct that is Type I error is possible.

Step by step solution

01

Given Information

We have to identify correct answer for the given data, X2=69.8with a P鈭� value of approximately 0. Assuming the researchers used a significance level of0.05 .

02

Simplification

When X2=69.8with a P value of nearly 0is presented as data, the correct answer is Type I mistake.
Assume that the researchers chose a 0.05significance threshold.

Thus, Option a) is correct.

Gummy bears Courtney and Lexi wondered if the distribution of color was

the same for name-brand gummy bears (Haribo Gold) and store-brand gummy bears

(Great Value). To investigate, they randomly selected bags of each type and counted the

number of gummy bears of each color.

Do these data provide convincing evidence that the distributions of color differ for name-

brand gummy bears and store-brand gummy bears?

Here are the data:

Tuition bills A random sample of U.S. adults was recently asked, 鈥淲ould you support or oppose major new spending by the federal government that would help undergraduates pay tuition at public colleges without needing loans?鈥� The two-way table shows the responses, grouped by age.

Do these data provide convincing evidence of an association between age and opinion about loan-free tuition in the population of U.S. adults?

Online banking A recent poll conducted by the Pew Research Center asked a random sample of 1846Internet users if they do any of their banking online. The table summarizes their responses by age. 23Is there convincing evidence of an association between age and use of online banking for Internet users?

What鈥檚 your sign? The University of Chicago鈥檚 General Social Survey (GSS) is the nation鈥檚 most important social science sample survey. For reasons known only to social scientists, the GSS regularly asks a random sample of people their astrological sign. Here are the counts of responses from a recent GSS of 4344 people:

If births are spread uniformly across the year, we expect all 12 signs to be equally likely. Do these data provide convincing evidence at the 1% significance level that all 12 signs are not equally likely?

Cocaine addicts need cocaine to feel any pleasure, so perhaps giving them an antidepressant drug will help. A 3-year study with 72chronic cocaine users compared an antidepressant drug called desipramine with lithium (a standard drug to treat cocaine addiction) and a placebo. One-third of the subjects were randomly assigned to receive each treatment. At the end of the study, researchers recorded whether or not the subjects relapsed. Which of the following conditions must be satisfied to perform the appropriate chi-square test using the data from this study?

I. The population distribution is approximately Normal.

II. The treatments were randomly assigned.

III. The observed counts are all at least 5.

a. I only

b. II only

c. III only

d. II and III

e. I, II, and III
