In testing Ho: P1 - P2 - 0 versus HAP1-P20 You obtain a test statistic with...
Consider the hypothesis test below. H. : P1 - P20 H. : P1 P2 > 0 The following results are for independent samples taken from the two populations. Sample 2 Sample 1 11 = 100 ©1 = 0.27 n2 = 300 P2 = 0.18 Use pooled estimator of p. a. What is the value of the test statistic (to 2 decimals)? .16 b. What is the p-value (to 4 decimals)? 1.89 c. With a = .05, what is your hypothesis...
Assume you have a hypothesis test as follows. Ho : P1 – P2 = 0 (HA: P1 – P2 70 You also know based on two surveys that: Survey 1: n1 =81, p =0.40 Survey 2: n2 =84.2 =0.22. Find the Z test statistic. Note: 1- Only round your final answer to 2 decimal places. Enter your final answer with 2 decimal places.
Consider testing H0: (p1-p2)=0 versus a two-tailed research hypothesis (H1: (p1-p2) not equal 0). Suppose you obtain a z test statistic equal to -2.37. Recalling that researchers typically report the best significance level reached among the conventional significance levels, the difference is statistically significant at a _____ percent level. (Type either 1, 5 or 10 to correctly fill in the blank.)
Consider the hypothesis test below. Ho: P 1 P2 0 Ha: P 1 P20 The following results are for independent samples taken from the two populations. Sample 1 1 200 P 1 0.27 Sample 2 n 2 300 P 2 0.18 Use pooled estimator of p. a. What is the value of the test statistic (to 2 decimals)? b. What is the p-value (to 4 decimals)? Use z-table. c. With a .05, what is your hypothesis testing conclusion? Select
Question 17 (1 point) Testing if P1 – P2 = 0.07, calculate the test statistic, z, where p from 65, and P2 = 0.23 sampled from 52. = 0.74 sampled Note: 1- Round any intermediate numbers to 4 decimal places. 2- Round your final answer to 2 decimal places. Enter your final answer with 2 decimal places
Test Hų: p– P2 = 0 versus H; P1 – P2 <0 Using a=0.05 and the following data: n=5600 number of success 30, m=5200 number of success 180 P-value=0.42 so Ho cannot be rejected O P-value=0.018<a so Ho should be rejected o Don't reject Ho because Z=-12 O Ho is rejected because - 4.18 < -2.33 O
Please help asap!!! Assume you have a hypothesis test as follows. Ho: P1 – P2 = 0 | 1 HA : p1 - P2 # 0 You also know based on two surveys that: Survey 1: N1 =90,Ể1 =0.45 Survey 2: N2 =82,P2 =0.15. Find the Z test statistic. Note: 1- Only round your final answer to 2 decimal places. Enter your final answer with 2 decimal places.
We are interested in testing the following hypotheses. H0: P1- P2 ³ 0, Ha: P1- P2 < 0. The test statistic Z is computed to be 0.58. The p-value for this test is A. 0.2810 B. 0.7190 C. 0.5620 D. 0.5800
Let P1 be the proportion of successes in the first population and let P2 be the proportion of successes in the second population. Suppose that you are testing the hypotheses: H. : P1 P2 = 0 Ha:P1 - P2 = 0 Futhermore suppose that z* = 1.73, find and input the p-value for this test. Round your answer to 4 decimal places. To answer the question input only the actual number. Do not include units. Do not give your answer...
