The following hypothesis test is to be conducted. Ho: Median ≤ 190 H₂: Median > 190 A sample of 30 provided 22 observations greater than 190, 3 observations equal to 190, and 5 observations less than 190. Use α = 0.01. Find the value of the test statistic. (Round your answer to two decimal places.) z = 2.56 X Find the p-value. (Round your answer to four decimal places.) p-value = 0.0052 X What is your conclusion? Reject Ho. The population median is less than or equal to 190. Do not reject Ho. The population median is less than or equal to 190. Reject Ho. The population median is greater than 190. Do not reject Ho. The population median is greater than 190.
We are testing a null hypothesis Ho:P1=P2 against an alternative hypothesis H7:P1 P2 where n = 50, x1 = 11, and n2 = 75, x2 =24. Find the value of the test statistic. 1.22 -1.89 -1.22 -.99
Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. H0: p=0.72 versus H1: p≠0.72 n=500, x=350, a=0.01
Compute the P-value. Round the answer to at least four decimal places. P-value = Part: 2/ 4 Part 3 of 4 Determine whether to reject H: Do not reject the null hypothesis Hg. Reject Do not reject
Use technology to find the P-value for the hypothesis test described below. The claim is that for 12 AM body temperatures, the mean is µ< 98.6°F. The sample size is n = 7 and the test statistic is t= P-value = (Round to three decimal places as needed.) hs
3042 You'd like to test the null hypothesis that the means of the two samples (column A and column B) are the same. The alternative hypothesis is that they are not the same. You have no reason to believe that the standard deviations of the two samples are equal. Test at the alpha = 0.10 level. After using Excel, what do you conclude? Are the means the same? Group of answer choices You cannot reject the null hypothesis. Therefore, you conclude that the means of the two populations are the same. You cannot reject the null hypothesis. Therefore, you conclude that the means of the two populations are different. You reject the null hypothesis. Therefore, you conclude that the means of the two populations are different. You reject the null hypothesis. Therefore, you conclude that the means of the two populations are the same.

A hypothesis test is performed at the 5% significance for a normal population mean u iwth the null and alternative hypotheses given below. Haitl# Ho Orl =r1:0H It is found that the p-value is p = 0.0123. What is the correct decision and interpretation of the hypothesis test? O Inconclusive or not enough information to tell. O Do not reject the null hypothesis. Our data supports the null hypothesis. O Do not reject the null hypothesis. We have proved the null hypothesis is true. O Reject the null hypothesis. We have proved the null hypothesis is false. O Reject the null hypothesis. Our data is statistically insignificant. O Reject the null hypothesis. Our data does not support the null hypothesis.
