Hypothesis Testing: Means and Proportions According to a 2017 survey, 80% of Americans used at least one type of social media regularly in 2017. Rodrigo wants to know if this percentage has decreased since then, so he collects some data. He randomly samples 200 people and finds that 154 of them still use at least one type of social media currently. Test the claim that less than 80% of Americans currently use at least one type of social media regularly. Use the 0.05 significance level.
Does more education lower a person’s level of prejudice? The number of years of education and the score on a prejudice test for ten people is given in the following table. Higher scores on the test indicate more prejudice. Years of Education: 12, 15, 14, 13, 18, 10, 16, 12, 10, 4 Score of Prejudice Test: 1, 6, 2, 3, 2, 4, 1, 5, 5, 10 Conduct a hypothesis test to determine if there is a significant linear correlation between the two variables. If there is a significant linear correlation between the variables, determine the regression equation. There is a significant correlation between the variables and the regression equation is y' = 10.5 - 0.532x There is a significant correlation between the variables and the regression equation is y' = - 0.532 + 10.5x There is not a significant correlation between the variables, so the regression equation should not be determined. There is a significant correlation between the variables and the regression equation is y' = 16.509 - 1.054x
QUESTION In the past, 29% of a country club's members brought guests to play golf sometime during the year. Last year, the club initiated a new program designed to encourage members to bring more guests to play golf. In a sample of 81 members, 29 brought guests to play golf after the program was initiated. When testing the hypothesis that the new program has increased the proportion of members bringing out guests (using a 5% level of significance), what is the test statistic? (please round your answer to 2 decimal places)

Hypothesis Test: Perform the specified hypothesis test. Be sure to include your statistical andin-context conclusion statements. In 1994, 52% of parents with children in high school felt it was a serious problem that high schoolstudents were not being taught enough math and science. A recent survey found that 512 of 1000 parentswith children in high school felt it was a serious problem that high school students were not being taughtenough math and science. Do parents feel different today than they did in 1994? Use the α = 0.005significance level.
