You may need to use the appropriate technology to answer this question. Consider the following hypothesis test. Ho: u 2 90 H:µ < 90 A sample of 100 is used and the population standard deviation is 12. Compute the p-value and state your conclusion for each of the following sample results. Use a = 0.01. (a) x = 88.5 Find the value of the test statistic. Find the p-value. (Round your answer to four decimal places.) p-value = State your conclusion. O Do not reject Ho: There is sufficient evidence to conclude that u < 90. O Do not reject Ho. There is insufficient evidence to conclude that u < 90. O Reject Ho. There is insufficient evidence to conclude that µ < 90. O Reject Ho. There is sufficient evidence to conclude that u < 90. (b) x = 87 Find the value of the test statistic. Find the p-value.

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.

For each of the following hypotheses in Questions 6-8, (i) provide the p-value (or its bounds) and (ii) draw a basic conclusion (REJECT or DO NOT REJECT only) with respect to Ho with 99% confidence. Handwritten notes are not necessary for these questions.
Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. H0: p=0.6 versus H1: p>0.6 n=250; x=1605, a=0.01 Is np 0 ( 1−p0) ≥10? Use technology to find the P-value.P-value?
