Use the following information to solve problems 12-15 A watchdog association claims that the percentage of Americans who agree that the government is inefficient and wasteful is different from 70%. A researcher wants to test this claim. The researcher conducts a survey and finds that out of a random sample of 1175 Americans, 785 agreed with this view. The standardized test statistic for a hypothesis test which tests whether the sample proportion is not equal to the hypothesized population proportion is equal to: b 2.378 c. 2.387 The probability value of the event that the standardized test statistic would assume a value as extreme or more extreme as that calculated in question 12 is: b. 0.017 c. 0.17 a. 0.0017 By comparing the probability value calculated in question 13 with a level of significance of 0.01 in a hypothesis test, we cannot reject the statement that a. the proportion of Americans who agree that the government is inefficient and wasteful is different from 70%. b. the proportion of Americans who agree that the government is inefficient and wasteful is equal to 70% c. the proportion of Americans who agree that the government is inefficient and wasteful is greater than 70% The minimum sample size necessary to estimate the population proportion with 99% confidence, so that the sample proportion differs from the population proportion by 5% is; a. 663 b. 664 c. 665 English (United States) Focus
