- x̅ = 50, µ =43, σ= 12 and n=16 conduct a two-tailed z-test. Use α = .01.A scientist suspects that as a person’s stress level changes, so does the amount of his or her impulse buying. With N = 72, his r is +.38. Using this given information complete the 6 step hypothesis test for correlations. Assume α = .05.The test statistic for a left-tailed test is z=-1.42. Solve for the P-value.
- An employer was wondering if employees perform better at work with music playing. They decide to run an experiment where they play music one day and no music on another day. Each day they calculate the average level of productivity and compare the two means. 1. Identify the null hypothesis and a directional alternative hypothesis. null duesn't increuse.Choose the correct answerTest the null hypothesis that the slope is zero versus the two-sided alternative in the following setting using the alpha=0.05 signifiance level. n=20, yhat=28.5+1.4x, and SEb1=0.65
- A research report includes the statement, “ z = 1.18, p > .05.” What happened in the hypothesis test? The obtained sample mean was very likely if the null hypothesis is true, so H0 was rejected. The obtained sample mean was very unlikely if the null hypothesis is true, and the test failed to reject H0. The obtained sample mean was very unlikely if the null hypothesis is true, so H0 was rejected. The obtained sample mean was very likely if the null hypothesis is true, and the test failed to reject H0.A sample of 32 observations is selected from a normal population. The sample mean is 32, and the population standard deviation is 6. Conduct the following test of hypothesis using the 0.05 significance level.H0: μ ≤ 29H1: μ > 29a. Is this a one- or two-tailed test?multiple choice 1 "One-tailed"—the alternate hypothesis is greater than direction. "Two-tailed"—the alternate hypothesis is different from direction. b. What is the decision rule? (Round your answer to 2 decimal places.) c. What is the value of the test statistic? (Round your answer to 2 decimal places.) d. What is your decision regarding H0?multiple choice 2 Do not reject Reject There is ______ evidence to conclude that the population mean is greater than 29. e. What is the p-value? (Round your answer to 4 decimal places.)Q3.) In an experiment, the following reading were recorded: Xi Yi 3.6 9.3 4.8 10.2 7.2 11.5 T 6.9 12 10.7 18.6 6.1 13.2 7.9 10.8 9.5 22.7 5.4 12.7 1- Derive the normalized equations for this reading if (y = a + bx) by LSA method. 2- Determine the best fitting of reading (theoretical values of y). 3- Estimate the value of y at x=2.5 Note: In solution of this question, approximate to three decimal digits (at maximum) only after the point.
- Q10. Suppose the alternative hypothesis for a particular test is given by H1: p ≠ 0.50. What is theP-value for this test if test statistic z = 1.35.a. 0.2010b. 0.0885c. 0.9115d. 0.1770Suppose that we have a problem for which the null and alternative hypothesis are given by: H0: μ = 88.5 ounces. H1:μ < 88.5 ounces. Is this a right-tailed test, left-tailed test, or two-tailed test. Find the z value based on a level of significance of α=.10.Find the two-tailed U-table value when n1 = 5, n2 = 6, and alpha = 0.05.
