A police officer claims that the proportion of accidents that occur in the daytime (versus nighttime) at a certain intersection is 35%. To test this claim, a random sample of 500 accidents at this intersection was examined from police records it is determined that 156 accidents occurred in the daytime. The following is the setup for this hypothesis test: {H0:p=0.35Ha:p≠0.35 Find the test statistic for this hypothesis test for a proportion. Round your answer to 2 decimal places.
Students in a high school statistics class are investigating the proportion of times a Hershey's Kiss would land flat on the base when tossed in the air. Some students think the proportion is less than 50% and some think the proportion is greater than 50%. To test this claim, the students tossed 80 Hershey's Kisses and determined the proportion of kisses that landed flat on the base. The resulting P-value is 0.0736. What conclusion would you make for the given significance test levels? For both a = 0.01 and a = 0.05, we would fail to reject Ho. There is not O convincing evidence the proportion of times the Hershey's Kiss will land flat on the base is different than 0.50 at either significance level. For only a = 0.05 we would reject Ho. There is convincing evidence the proportion of times the Hershey's Kiss will land flat on the base is different than 0.50 at a = 0.05, but not at a = 0.01 For both a = 0.01 and a = 0.05, we would reject Ho.

For all hypothesis testing, you must use the five-step method. You want to know whether in the population, men and women differ in terms of their internet use. You draw random samples of men and women, and ask them the following question: "In the past seven days, has the total amount of time you spent using the internet exceeded twelve hours?" The respondents answer "yes" or "no." The percentage answering "yes" and the sample sizes are given below. In the population, is there a difference between men and women regarding internet use? Set alpha at .05. Your hunch is that there is a difference between men and women in the population, but you make no claims about the direction of the difference. Round to two places of the decimal. Interpret your results. Men Women 21% say "yes" 16% say…
K The following data represent the level of health and the level of education for a random sample of 1761 residents.
