In order to compare the means of two normal populations with equal variances, independentrandom samples are taken of sizes n = 12 and n2 8. The results from the sample data yield:Sample 1Sample 2sample mean =52 sample mean = 48S1= 1.152 = 2.4To test the null hypothesis Ho: H1 - H2 = 0 versus the alternative hypothesis H, H1- 2 0 at the0.01 level of significance, the most accurate statement isO The value of the test statistic is 5.08 and the critical value is +2.552O The value of the test statistic is 2.8 and the critical value is +2.552O The value of the test statistic is 2.8 and the critical values are -2.552 and +2.552O The value of the test statistic is 5.08 and the critical value is +2,528O The value of the test statistic is 5.08 and the critical value is 2.326

Only about 18% of all people can wiggle their ears. Is this percent lower for millionaires? Of the 326 millionaires surveyed, 49 could wiggle their ears. What can be concluded at the αα = 0.01 level of significance? For this study, we should use Correct The null and alternative hypotheses would be: H0: (please enter a decimal) H1: (Please enter a decimal) The test statistic = ? (please show your answer to 4 decimal places.) The p-value = ? (Please show your answer to 4 decimal places.) The p-value is <OR > α? Based on this, we should ACCEPT OR REJECT OR FAIL TO REJECT the null hypothesis ?
