Chapter 8: Q. 9.59 (page 370)

We have given the P-value for a hypothesis test. For each exercise determine the strength of the evidence against null hypothesis.

Given P-valueis0.184

Short Answer

Expert verified

The P-value is 0.184, which is higher than the threshold of 0.01.

As a result of the circumstances, it's clear that the null hypothesis has little or no support.

Step by step solution

01

Step 1. Given

The givenP-valueis0.184.

02

Step 2. Conditions for evaluating strength of the evidence 

Criteria for testing the strength of evidence from P values:

-0.10< P-value, weak or no evidence to contradict the null hypothesis.

-0.05<P-value鈮�0.10, moderate evidence contradict t the null hypothesis.

-0.01<P-value<0.05, strong evidence contradict the null hypothesis.

-P-value<0.01,the strongest evidence contradict the null hypothesis.

03

Step 3. Conclusion

The P-value is 0.184, which is higher than the threshold of 0.01.

That is, P-value(=0.184)>0.01.

As a result of the circumstances, it's clear that the null hypothesis has little or no support.

Testing Claims About Proportions. In Exercises 9鈥�32, test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, or critical value(s), then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Use the P-value method unless your instructor specifies otherwise. Use the normal distribution as an approximation to the binomial distribution, as described in Part 1 of this section.

Touch Therapy Repeat the preceding exercise using a 0.01 significance level. Does the conclusion change?

OxyContin The drug OxyContin (oxycodone) is used to treat pain, but it is dangerous because it is addictive and can be lethal. In clinical trials, 227 subjects were treated with OxyContin and 52 of them developed nausea (based on data from Purdue Pharma L.P.). Use a 0.05 significance level to test the claim that more than 20% of OxyContin users develop nausea. Does the rate of nausea appear to be too high?

A formal hypothesis test is to be conducted using the claim that the mean height of men is equal to 174.1 cm.

a. What is the null hypothesis, and how is it denoted?

b. What is the alternative hypothesis, and how is it denoted?

c. What are the possible conclusions that can be made about the null hypothesis?

d. Is it possible to conclude that 鈥渢here is sufficient evidence to support the claim that the mean height of men is equal to 174.1 cm鈥�?

In Exercises 1鈥�4, use these results from a USA Today survey in which 510 people chose to respond to this question that was posted on the USA Today website: 鈥淪hould Americans replace passwords with biometric security (fingerprints, etc)?鈥� Among the respondents, 53% said 鈥測es.鈥� We want to test the claim that more than half of the population believes that passwords should be replaced with biometric security.

Null and Alternative Hypotheses Identify the null hypothesis and alternative hypothesis.

Test Statistics. In Exercises 13鈥�16, refer to the exercise identified and find the value of the test statistic. (Refer to Table 8-2 on page 362 to select the correct expression for evaluating the test statistic.)
