Information #17-18In recent years, there has been considerable controversy over the use of standardized testing of high school students. Supporter say that the practice is a good measure of both student, progress and teacher performance. Opponents say that too much testing impedes learning, and causes unnecessarily large expenses for the school districts. There are even reports that a significant number of high school students opt out of taking some of the standardized tests. In one large city, where the school District reported that the average score in a national test taken by students in their junior year was 74, a large group of parents felt that this average was too low. The parents contracted a research company in an attempt to show that the average score was higher than the claimed average of 74. The research company took a random sample of 100 juniors and they collected the corresponding 100 exam scores for those students.

D Question 17 1 pts If the alternate hypothesis were modified in this problem to be a two-sided test using a not equal to symbol in the alternative hypothesis, and the test statistic turned out to be z = -1.59, then what is the p-value? O 0.1069 O 0.0559 O 0.1118 O 0.1297 D Question 18 1 pts If the p-value for the test is 0. 0906, choose the most appropriate conclusion for the hypothesis test (Assume a significance level of 10%). At the 10% significance level there is sufficient evidence to support the belief of the group of parents that the true mean of the national test scores is higher than the school district reported average of 74. At the 10% significance level there is sufficient evidence to support the belief of the group of parents that the true mean of the national test scores is lower than the school district reported average of 74. At the 10% significance level there is insufficient evidence to support the belief of the group of parents that the true mean of the national test scores is lower than the school district reported average of 74. At the 10% significance level there is insufficient evidence to support the belief of the group of parents that the true mean of the national test scores is higher than the school district reported average of 74
