According to the National Highway and Traffic Safety Administration, the proportion of fatal traffic accidents in the United States in which the driver had a positive blood alcohol concentration (BAC) is .36. Suppose a random sample of 105 traffic fatalities in the state of Hawaii results in 51 that involved a positive BAC. D) Check whether the conditions for hypothesis testing using the P-value approach are meet.
In a study of 810 randomly selected medical malpractice lawsuits, it was found that 499 of them were dropped or dismissed. Use a 0.05significance level to test the claim that most medical malpractice lawsuits are dropped or dismissed. Which of the following is the hypothesis test to be conducted? A. H0: p=0.5 H1: p≠0.5 B. H0: p=0.5 H1: p>0.5 C. H0: p>0.5 H1: p=0.5 D. H0: p=0.5 H1: p<0.5 E. H0: p<0.5 H1: p=0.5 F. H0: p≠0.5 H1: p=0.5 What is the test statistic? z= ? (Round to two decimal places as needed.) What is the P-value? P-value= ? (Round to three decimal places as needed.) What is the conclusion about the null hypothesis? A. Reject the null hypothesis because the P-value is less than or equal to the significance level, α. B. Fail to reject the null hypothesis because the P-value is greater than the significance level, α. C. Fail to reject the null hypothesis because…
A national publishing house claims that 45% of all weekly magazine readers in South Africa read their publication. Test this claim at the 5% significance level, if a survey found that 205 out of a random sample of 500 magazine readers said that they read the relevant publication. Remember to use the five steps in the hypothesis testing procedure for the answer
A machine in a factory must be repaired if it produces more than 10% defectives in a day. A random sample of 100 produced items contains 15 defectives, and the supervisor says that the machine must be repaired. Given the aforementioned information and the hypotheses H0: p ≤ 0.1 and H1: p > 0.1, does the sample support the supervisor's decision at the 0.01 significance level?
If, in a one-tail hypothesis test where H0 is only rejected in the upper tail, the p-value=0.2047 and ZSTAT=+0.82, what is the statistical decision if the null hypothesis is tested at the 0.07 level of significance? What is the statistical decision?
A medical researcher claims that 5% of children have asthma.In a random sample of 100 children 7.2% say they have asthma. At α=.05, evaluate the claim by: Identifying the claim and H0 and Ha, Finding the appropriate standardized test statistic, Finding the P-value or the rejection region, Deciding whether to reject or fail to reject the null hypothesis, and Interpreting the decision in the context of the original claim.
* In a certain state, a referendum is being held to determine whether the transportation authority should issue additional highway bonds. A sample of 430 voters is taken in county A, and 235 say that they favor the bond proposal. A sample of 500 voters is taken in county B, and 265 say that they favor the bond issue. Perform a hypothesis test to measure the strength of the evidence that the proportion of voters who favor the proposal is greater in county A than in county B. Use the a=0.02 level of significance. Use P Method and list all 6 steps clearly.
In a certain state, a referendum is being held to determine whether the transportation authority should issue additional highway bonds. A sample of 550 voters is taken in county A, and 245 say that they favor the bond proposal. A sample of 600 voters is taken in county B, and 275 say that they favor the bond issue. Perform a hypothesis test to measure the strength of the evidence that the proportion of voters who favor the proposal is greater in county A than in county B. Use the α = 0.02 level of significance.
It has been claimed that more than 40 percent of allshoppers can identify a highly advertised trademark. If, in a random sample, 10 of 18 shoppers were able to iden-tify the trademark, test at the 0.05 level of significance whether the null hypothesis θ = 0.40 can be rejectedagainst the alternative hypothesis θ > 0.40.
a. Set up null and alternative hypotheses to try to determine whether there is a difference in ad impact between general TV viewing and VOD viewing. Conduct the hypothesis test defined in (a), using the 0.05 level of significance.
Conduct the appropriate hypothesis test and compute the p-value. Sunshine Air has determined that their no-show rate for passengers booked on a flight is 6%. The Airline has recently increased the cost of its travel insurance and and suspects the no-show rate for passengers will decrease. A random sample of 380 reservations resulted in 18 no-shows. At the 0.10 significance level, is there strong enough sample evidence to suggest that the no-show rate in less than 6%?
In a study of 776randomly selected medical malpractice lawsuits, it was found that 513 of them were dropped or dismissed.
