Assume that a simple random sample has been selected and test the given claim. Use the​ P-value method for testing hypotheses. Identify the null and alternative​ hypotheses, test​ statistic, P-value, and state the final conclusion that addresses the original claim. The ages of actresses when they won an acting award is summarized by the statistics n= 85​, x= 35.7 years, and s= 11.3 years. Use a 0.01 significance level to test the claim that the mean age of actresses when they win an acting award is 32 years.

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. A simple random sample of front-seat occupants invol ved in car crashes is obtained. Among 2823 occupants not wearing seat belts, 31 were killed. Among 7765 occupants wearing seat belts, 16 were killed. We want to use a 0.05 significance level to test the claim that seat belts are effective in reducing fatalities. Test the claim using a hypothesis test.

Among 7765 occupants wearing seat belts, 16 were killed. We want to use a 0.05 significance level to test the claim that seat belts are effective in reducing fatalities. Test the claim by constructing an appropriate confidence interval.

In a recent court case it was found that during a period of 11 years

people were selected for grand jury duty and

​%

of them were from the same ethnicity. Among the people eligible for grand jury​ duty,

​%

were of this ethnicity. Use a

significance level to test the claim that the selection process is biased against allowing this ethnicity to sit on the grand jury. Identify the null​ hypothesis, alternative​ hypothesis, test​ statistic, P-value, conclusion about the null​ hypothesis, and final conclusion that addresses the original claim. Use the​ P-value method and the normal distribution as an approximation to the binomial distribution.

 

  1. Which of the following is the hypothesis test to be​ conducted?
  2. What is the test statistic?
  3. What is the P value?
