In a survey conducted by the Pew Reasearch Center in the U.S. from September 7 to 12 in 2021, 85% of 1,008 respondents said that the relations between the U.S. and Germany were good. 1) Let p denote the population proportion of Americans who thought that the relations between the U.S. and Germany were good. State the null and alternative hypothesis of a two-sided significance test comparing p with 80%. 2) Calculate the test statistics and find the p-value. 3) What conclusion can you make for this test, using the significance level α(alfa)=0.01?

A new online test preparation company compared 3,025 students who had not used its program with 2,150 students who had. Of those students who did not use the online test preparation program, 1,513 increased their scores on the SAT examination compared with 1,100 who did use the program. A significance test was conducted to determine whether there is evidence that the online test preparation company's students were more likely to increase their scores on the SAT exam. What is the p-value for an appropriate hypothesis test?

According to the Centers for Disease Control and Prevention (CDC), the mean BMI of U.S. men of age 40–49 years old is 28.4 Using the provided sample data file, conduct a one-sample ?-z-test of a mean to test whether the mean BMI of men of age 40–49 years old who smoke daily is lower than 28.4. Conduct the ?-z-test at a significance level of ?=0.05 to test the null hypothesis, ?0:?=28.4, against the alternative hypothesis, ?1:?<28.4, where ?μ represents the mean BMI of U.S. men of age 40–49 who smoke daily. Assume that the population standard deviation of BMI, ?σ, is 8.346 The sample data provided contain BMI results collected from a 2015 survey conducted by the National Center for Health Statistics for men of age 40–49 who smoke daily.

As part of a recent survey among dual-wage-earner couples, an industrial psychologist found that 990 men out of the 1,500 surveyed believed the division of household duties was fair. A sample of 1,600 women found 970 believed the division of household duties was fair. At the 0.01 significance level, is it reasonable to conclude that the proportion of men who believe the division of household duties is fair is larger? State the null and alternate hypotheses. Make the decision rule. (Round your answer to 2 decimal places.) Evaluate the test statistic. (Round your answer to 2 decimal places.)
