Question 20 In a two-sided z-test, the test statistic was 1.39. What is the p-value? Do...
the test statistic of z = 1.39 is obtained when testing the claim that p>0.8. a. Identify the hypothesis test as being two tailed, left tailed, or right tailed. b. Find the P-value. c. Using a significance level alpha = 0.05, should we reject Ho or should we fail to reject Ho? d. What is the correct conclusion for this test?
A test statistic for a two sided significance test for a population mean is z=2.31. Sketch a standard Normal curve and mark this value of z on it. Find the P-value and shade the appropriate areas under the curve to illustrate your calculations.
3. ________ In a two-sided hypothesis test, the observed test statistic is determined to be Z = -2.5. The p-value for this test is (A) 0.1091 (B) 0.0538 (C) 0.0062 (D) 0.0124 Can you explain your answer? thank you
For each test statistic below, give the p value (do not round p): a. t = 2.20, df = 15, one-tailed test b. Z = 1.10, one-tailed test c. t = -2.65, df = 20, two-tailed test d. Z = -.26, two-tailed test
What is the p-value for a two tailed test when the test statistic is z=0.7? 0.484 0.089 0.242 0.944
What is the p-value of a two-tailed one-mean hypothesis test, with a test statistic of z0=−1.73? (Do not round your answer; compute your answer using a value from the table below.) z−1.8−1.7−1.6−1.5−1.40.000.0360.0450.0550.0670.0810.010.0350.0440.0540.0660.0790.020.0340.0430.0530.0640.0780.030.0340.0420.0520.0630.0760.040.0330.0410.0510.0620.0750.050.0320.0400.0490.0610.0740.060.0310.0390.0480.0590.0720.070.0310.0380.0470.0580.0710.080.0300.0380.0460.0570.0690.090.0290.0370.0460.0560.068
Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. Use either the T Calculator or the Normal Calculator to compute the P-value of the following test statistics. (a) The test statistic in a two-tailed is z = 1.39. Round to four decimal places. (b) Find the P-value for a right-tailed test with n = 27 and test statistic t = 1.502. Round to...
The value of the test statistic for a two-tailed one-mean z-test is z 1.52. Determine the p-value. (Round to four decimal places.) Answer: 0.1285
1. Find the P-value for the indicated hypothesis test with the given standardized test statistic, z. Decide whether to reject Upper H 0 for the given level of significance alpha. Two-tailed test with test statistic z= -1.95 and alpha=0.04 P-value= ? (Round to four decimal places as needed.) Reject H0 or fail to reject? 2. Find the critical value(s) for a left-tailed z-test with alpha=0.01. Include a graph with your answer. The critical value(s) is(are) ___ (Round to two...
The test statistic in a two dash tailed test is z= -2.84. Determine the P-value and decide whether, at the 1% significance level, the data provide sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis. *Please show me a way to do it on the calculator (ti-84)*
