Calculate the p-value for a two-tailed hypothesis test with test statistic z = - 1.80 that

What is the p-value of a right-tailed one-mean hypothesis test, with a test statistic of z0=1.6? (Do not round your answer; compute your answer using a value from the table below.)

Two treatments for a new infectious disease have been developed to reduce hospitalizations. Each treatment was given to different groups of patients. Treatment 1 was given to 65 people. Subjects of treatment 1 had a mean hospital stay of 5.6 days with a standard deviation of 2.6 days. Treatment 2 was given to 54 people. Subjects of treatment 2 had a mean hospital stay of 8.4 days with a standard deviation of 3.0 days. Use the method of hypothesis testing to test the claim that the mean time in the hospital for treatment 1 is shorter than the mean time in the hospital for treatment 2 assuming a 0.05 significance level. (a) List the null and alternative hypotheses for this test. (b) Compute the value of the test statistic (c) Determine the rejection region.(d) Determine whether or not we can reject the null hypothesis.

What is the p-value of a right-tailed one-mean hypothesis test, with a test statistic of z0=2.05? (Do not round your answer; compute your answer using a value from the table below.)

Find the P-value for the indicated hypothesis test with the given standardized test statistic, z. Decide whether to reject H, for the given level of significance a. Two-tailed test with test statistic z = - 1.69 and a = 0.07 P-value = (Round to four decimal places as needed.)

For a one-tailed (upper tail) hypothesis test with a sample size of 26 and a .01 level of significance, the critical value of the test statistic t is

In the past, the time for Jeff's journey to work had mean 45.7 minutes and standard deviation 5.6 minutes. This year he is trying a new route. In order to test whether the new route has reduced his journey time, Jeff finds the mean time for a random sample of 30 journeys using the new route. He camies out a hypothesis test at the 2.5% significance level. Jeff assumes that, for the new route, the joumey time has a nomal distribution with standard deviation 5.6 minutes. (a) State appropriate null and alternative hypotheses for the test. (b) Determine the rejection region for the test.

The manager of a driving school claims that the mean time taken to learn how to drive a car is 8 hours for all new drivers. A sample of 16 new drivers showed that the mean time taken by them to learn how to drive a car is 9.5 hours with a standard deviation of 1.5 hours. Test at the 1% significance level if the mean time taken to learn how to drive a car by all new drivers is greater than 8 hours.

Find the P-value for the indicated hypothesis test with the given standardized test statistic, z. Decide whether to reject Ho for the given level of significance a. Right-tailed test with test statistic z = 1.00 and a = 0.04 ..... P-value = (Round to four decimal places as needed.)
