The test statistic of z=2.75 is obtained when testing the claim that p≠0.317.   a. Identify the hypothesis test as being​ two-tailed, left-tailed, or​ right-tailed. b. Find the​ P-value. c. Using a significance level of α=0.10​, should we reject H0 or should we fail to reject H0​?

B. Identify the test statistic Z=___ C. Identify the​ P-value. P-value=___ D. What is the conclusion based on the hypothesis​ test? The​ P-value is (greater than/less than) the significance level of α=0.01​,so (reject/ fail to reject) the null hypothesis. There is (suffiecient/ insufficient) evidence to support 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 by constructing an appropriate confidence interval. The 90​% confidence interval is ___<( p1-p2)<___   E. Because the confidence interval limits (do not include/include) 0, it appears that the two proportions are (equal/not equal) Because the confidence interval limits include (only negative/ only positive/ negative and positive) values, it appears that the proportion of people over 55 who dream in black and white is (greater than/less than/ not significantly different from) the proportion for those under 25.   F. An explanation…

The test statistic of z=1.50 is obtained when testing the claim that p≠0.427. Identify the hypothesis test as being​ two-tailed, left-tailed, or​ right-tailed. Find the​ P-value. Using a significance level of α=0.10​, should we reject H0 or should we fail to reject H0​? I am stuck on 2

Find the P-value that corresponds to the given standard score, and determine whether to reject the null hypothesis at the 0.05 significance level. Is the alternative hypothesis supported? z=2.6 for Hoμ=149 pounds and H₂: μ* 149 pounds

Test the claim that the mean GPA of night students is larger than 2.1 at the 0.05 significance level. The null and alternative hypothesis would be: Ho: 4 2.1 H1:p + 0.525 H1:p > 0.525 0.525 Ho:p 2.1 Ho:p > 0.525 Н:р + 2.1 Н:n < 2.1 Ні:р < 0.525 The test is: two-tailed right-tailed left-tailed Based on a sample of 55 people, the sample mean GPA was 2.14 with a standard deviation of 0.02 The p-value is: (to 2 decimals) Based on this we: Reject the null hypothesis Fail to reject the null hypothesis

The test statistic of z = 2.05 is obtained when testing the claim that p > 0.4. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. Find the P-value. Using a significance level of α = 0.10, should we reject H0 or should we fail to reject H0?

The test statistic of z=2.77 is obtained when testing the claim that p≠0.684. a. Identify the hypothesis test as being​ two-tailed, left-tailed, or​ right-tailed. b. Find the​ P-value. c. Using a significance level of α=0.10​, should we reject H0 or should we fail to reject H0​?

Test the claim that the mean GPA of night students is larger than the mean GPA of day students at the .01 significance level.The null and alternative hypothesis would be: H0:pN=pDH0:pN=pDH1:pN>pDH1:pN>pD H0:pN=pDH0:pN=pDH1:pN<pDH1:pN<pD H0:μN=μDH0:μN=μDH1:μN>μDH1:μN>μD H0:μN=μDH0:μN=μDH1:μN<μDH1:μN<μD H0:μN=μDH0:μN=μDH1:μN≠μDH1:μN≠μD H0:pN=pDH0:pN=pDH1:pN≠pDH1:pN≠pD The test is: two-tailed right-tailed left-tailed The sample consisted of 25 night students, with a sample mean GPA of 3.43 and a standard deviation of 0.03, and 30 day students, with a sample mean GPA of 3.38 and a standard deviation of 0.02.The test statistic is: ______ (to 2 decimals)The critical value is:  ________(to 2 decimals)Based on this we: Fail to reject the null hypothesis Reject the null hypothesis

Use the given information to find the P-value. Also, use a 0.05 significance level and state theconclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis).With H1: p (does not equal) 3/5, the test statistic is z = 0.78

The test statistic of z = 0.53 is obtained when testing the claim that p > 0.5. Identify the hypothesis test as being​ two-tailed, left-tailed, or​ right-tailed. Find the​ P-value. Using a significance level of α = 0.05​, should we reject H0 or should we fail to reject H0​?
