The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject He when the level of significance is (a) a = 0.01, (b) a = 0.05, and (C) a = 0.10. P = 0.0695 (a) Do you reject or fail to reject He at the 0.01 level of significance? O A. Fail to reject H, because the P-value, 0.0695, is greater than a = 0.01. O B. Fail to reject H, because the P-value, 0.0695,...

A hypothesis test is performed at the α = 0.05 level of significance. The p-value is determined to be 0.03. Therefore, we know that we would _______________. either reject or fail to reject the null hypothesis, depending on the value of the test statistic. reject the null hypothesis know that a 99% confidence interval would contain the value specified in the null hypothesis. fail to reject the null hypothesis

A random sample of 86 eighth grade students' scores on a national mathematics assessment test has a mean score of 267. This test result prompts a state school administrator to declare that the mean score for the state's eighth graders on this exam is more than 260. Assume that the population standard deviation is 31. At α=0.12, is there enough evidence to support the administrator's claim? Complete parts (a) through (a) Write the claim mathematically and identify Ho and H...
