- You want to run a hypothesis test on the proportion of a phenomenon occurring. You make the following choices: Significance level: 5% Null Hypothesis: p >= 0.6 Alternate Hypothesis: p < 0.6 A sample is then taken with the following properties: A sample size of 120 A sample proportion of 0.54 Run a hypothesis test and either reject or do not reject the null hypothesis.arrow_forwardFind the value of the standard score, z, and determine whether to reject the null hypothesis at a 0.10 significance level. Is the alternative hypothesis supported? Ho: p= 19.6 seconds, H: p> 19.6 seconds, n = 121, x=20 5 seconds, o = 2.0 seconds a The value of the standard score is (Round to two.decimal places as needed.)arrow_forwardA hypothesis test is performed on the following where the claim is the null hypothesis Ho:p = 0.74 H :p+0.74 a.) What population parameter is being tested? a. proportion b. standard deviation C. mean d. variance b.) What type of hypothesis test is being performed? a. left-tailed b. right-tailed c. two-tailedarrow_forward
- Which of the following is the correct way to report the results of a hypothesis test and a measure of effect size using a tstatistic? a. r2 = 0.42, t(19) = 2.30 , p < .05 b. t(19) = 2.30, p < .05, r2 = 0.42 c. t = 2.30, df = 19, p < .05, r2 = 0.42 d. t(19) = 2.30, r2 = 0.42, p < .05arrow_forwardAccording to a University Center for Logistics Management, 8% of all merchandise sold in the United States gets returned. Seattle department store sampled 88 items sold in January and found that 8 of the items were returned. If you have the following null and alternative hypotheses for a test you are running: Ho:p = 0.08 Ha:p < 0.08 Calculate the test statistic, rounded to 3 decimal places.

- Men Women H2 A study was done on body temperatures of men and women. The results are shown in the table. Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. 11 97.67°F 0.91°F 59 97.35°F 0.73°F a. Use a 0.05 significance level to test the claim that men have a higher mean body temperature than women. What are the null and alternative hypotheses? OB. Ho H =H2 O A. Ho 4, 2H2 H: 1arrow_forwardThe smaller the observed p-value, the more evidence you have against the null hypothesis. Select one: True Falsearrow_forwardUsing image attached A. Fill in blanks B. What are the null and alternative hypothesis? C. Find the test statistic, z0 D.

Ho p= 18.5 meters, H p18.5 meters, n= 144, x = 19.1 meters, o = 1.3 meters %3D The value of the standard score is (Round to two decimal places as needed.)arrow_forwardTina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds.
