5.b. Test statistic = ?c. P-value = ? d. Reject/Accept null hypothesis ? Consider a drug that is used to help prevent blood clots in certain patients. In clinical trials, among 5824 patients treated with this drug, 149developed the adverse reaction of nausea. Use a 0.10 significance level to test the claim that 3% of users develop nausea. Does nauseaappear to be a problematic adverse reaction?

For a one-tailed hypothesis test (upper tail) the p-value is computed to be 0.008. If the test is being conducted at 99% confidence, the null hypothesis could be rejected or not rejected depending on the sample size could be rejected or not rejected depending on the value of the mean of the sample is not rejected is rejected
1) If your p-value is less than a significance level , then your decision is to fail to reject the null hypothesis. True or False 2)The test statistic, z, in a hypothesis test measures the difference between the sample proportion and the hypothesized proportion in terms of standard deviations. True or False
What is the value of the test statistic for a test with a null hypothesis that mu = 100, Xbar = 110, the standard error = 20 and n = 49?
How would a person set up the hypotheses if they wanted to test the claim: the mean length of a Pyramid Lake trout is greater than 21 inches? What would be a type Il error in this case? O State the mean length of a Pyramid Lake trout is greater than or equal to 21 inches when in fact the mean length of a Pyramid Lake trout is less than 21 inches. State the mean length of a Pyramid Lake trout is less than or equal to 21 inches when in fact the mean length of a Pyramid Lake trout is greater than 21 inches. State the mean length of a Pyramid Lake trout is less than 21 inches when in fact the mean length of a Pyramid Lake trout is greater than or equal to 21 inches. O State the mean length of a Pyramid Lake trout is greater than 21 inches when in fact the mean length of a Pyramid Lake trout is less than or equal to 21 inches.
The Woodcock-Johnson Cognitive Ability test indicates that the average score is 95. The same group of 12th grade students (n = 72) in Columbus are tested and the sample mean is 110.1 and the sample standard deviation is 15.2. Do the scores provide good evidence that the mean IQ of this population is greater than 95? What is the p-value for this data what is your decision about the null hypothesis? reject or fail to reject?
What is the value of the test statistic for a test with a null hypothesis that mu = 83, Xbar = 85, the sample standard deviation = 2 and n = 49?
A small p-value means that the probability of obtaining a sample mean more extreme than the one observed is low under the null. True or False?
What is the value of the test statistic for a test with a null hypothesis that mu = 82, Xbar = 85, the standard error = 5 and n = 100?
In the past, the mean running time for a certain type of flashlight battery has been 8.1 hours. The manufacturer has introduced a change in the production method and wants to perform a hypothesis test to determine whether the mean running time has changed as a result. This test would be a (a) left-tailed test (b) two-tailed test (c) right-tailed test The test is (Enter a, b, or c)
4. What calculation is used as an absolute estimate of the reliability of a test, taking into account the units of the test, and not being sensitive to between-subject variability?
