A bank manager is interested in if the mean time it takes for customers to beserved at their branch is 8 minutes. Having taken a random sample of customerwaiting times, the manager performs a hypothesis test and finds a p-value of0.03. At the 5% significance level, the conclusion of the test will be:A.B.C.D.E.As only the p-value is provided, there is not enough information to beable to decide whether to reject or not reject the null hypothesis at the5% significance level.The results suggest that, at the 5% significance level, the populationmean waiting time is not 8 minutes.The results suggest that, at the 5% significance level, the populationmean waiting time is in fact 0.03 minutes.The results suggest that, at the 5% significance level, the manager isunable to reject the null hypothesis, that the population mean waitingtime is 8 minutes.None of the above.The mean represents:A. the arithmetic average of a data distributionB. the degree of kurtosisC. the most frequently occurring value in a distributionD. the degree of skewnessE. the midpoint of a data distribution

A person is directing a hypothesis test, to check: Ho: μ = 5000 verses HA: μ < 5000. Test is to be directed using 10% significance level. To do this test, a random sample was chosen and examined, resulting in a p-value of .035. Using 10% significance level does the person have enough evidence to conclude that; μ < 5000?
Do the needs of patients in the emergency room differ for those who come by car vs. those by ambulance? Of the randomly selected emergency room patients who came by car 51 had an injury, 40 were sick, 31 had heart problems and 61 had other needs. Of the randomly selected emergency room patients who came by ambulance 45 had an injury, 30 were sick, 55 had heart problems and 38 had other needs. Conduct the appropriate hypothesis test using an a = 0.10 level of significance. a. What is the correct statistical test to use? O Paired t-test O Homogeneity Goodness-of-Fit O Independence b. What are the null and alternative hypotheses? Ho: O Means of transportation to the emergency room and emergency room needs are independent. Means of transportation to the emergency room and emergency room needs are dependent. The distribution of emergency room needs for patients who come by car is the same as it is for patients who come by ambulance. The distribution of emergency room needs for patients who…
A researcher looking for evidence of extrasensory perception (ESP) tests 1000 subjects. Forty-three of these subjects do significantly better (P < 0.05) than random guessing. Forty-three seems like a lot of people, but you cannot conclude that these 43 people have ESP. Why not? The statistical significance level is not be stringent enough to conclude an ESP status. Since the tests were performed at the 5% significance level, as many as 50 subjects may have done significantly better than random guessing just by chance. The sample size was not large enough for any statistical inference. The P-value needs to be below 0.025 to be considered statistically significant given the two-tailed nature of this type of test.
A pharmaceutical company claims that the mean time it takes for their new pain relief medication to take effect is 20 minutes. A sample of 12 patients is randomly selected and given the medication. The time it takes for each patient to feel the effects of the medication (in minutes) is recorded as follows: 23, 19, 17, 22, 22, 23, 20, 23, 19, 21, 18, 25 a) Conduct a hypothesis test with a significance level of 0.05 to determine if there is evidence to support the company's claim. b) Calculate a 95% confidence interval for the true mean time it takes for the medication to take effect.
A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 285 people over the age of 55, 76 dream in black and white, and among 287 people under the age of 25, 10 dream in black and white. Use a 0.01 significance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25. Test the claim using a hypothesis test. Consider the first sample to be the sample of people over the age of 55 and the second sample to be the sample of people under the age of 25. What are the null and alternative hypotheses for the hypothesis test? O A. Ho: P1 = P2 H: P1> P2 O B. Ho: P1 = P2 OC.

A researcher wants to know if mood is affected by music. She conducts a test on a sample of 4 randomly selected adults and measures mood rating before and after being exposed to classic rock music. Test the hypothesis that mood rating decreased after being exposed to classic rock music. The mood ratings for the four participants are provided. Assume that all conditions for testing have been met. Report the null and alternative hypothesis and p-value. At the 1% significance level, state the decision regarding the null hypothesis and the conclusion about the original claim. Round all values to the nearest thousandth. Click the icon to view the mood ratings. OA. Ho Hdifference =0, Ha Hdifference >0; p=0.373; Reject the null hypothesis; there is strong evidence to suggest that exposure to classic rock music decreased mood rating. B. Ho Hdifference =0, Ha Hdifference >0; p=0.373; Fail to reject the null hypothesis; there is not strong evidence to suggest that exposure to classic rock music…
