When debating the state appropriation for Penn State, the following question is asked: "Are the majority of students at Penn State from Pennsylvania?" (A majority is anything higher than 0.5). The school claims that there is a majority of students from Pennsylvania. A random sample of 500 students is taken and it is found that 278 of them are from Pennsylvania. Find the test statistic and p-value for this test. Round to two decimal places.

Suppose the Humane Society claims that 30% of U.S. households own cats. You believe your community is different than the U.S. percentage. To test the claim, you take a simple random sample of 300 households and find that 33% own cats. Test at 5% significance. Round to the fourth Ho: P HA: P How many successes were there? 111 X Test Statistic: 2.646 X P-value: 0.995 X Did something significant happen? Nothing Significant Happened Select the Decision Rule: Fail to Reject the Null or There is not o enough evidence to conclude that the proportion of households that own cats in your community is different than the national proportion.

A publisher reports that 29%of their readers own a particular make of car. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage. A random sample of 250 found that 26% of the readers owned a particular make of car. Determine the P-value of the test statistic. Round your answer to four decimal places.
The Census Bureau's American Housing Survey has reported that 76 percent of families choose their house location based on the school district. You want to conduct a test of whether the population proportion really equals 0.76. Use a 0.10 level of significance and a sample of 440. The proportion of families in your sample that choose their home based on the school district was 0.78. a. State in statistical terms the null and alternative hypotheses. (2 points) b. Determine the appropriate test statistic. (z or t) (2 points) c. Determine the critical values. (2 points) d. Compute the test statistic. (2 points) e. Make a decision on the hypotheses. (which hypothesis is correct?) (2 points)
Hypothesis Testing Review For each problem below, simply identify the null and alternative hypotheses. Use appropriate notation/symbols. You do not have to run any hypothesis tests, although it's good practice and I'll post answers for all of them. 1) A simple random sample of 44 men from a normally distributed population results in a standard deviation of 10.7 beats per minute. The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normal range, the result is a standard deviation of 10 beats per minute. Use the sample results with a 0.10 significance level to test the claim that pulse rates of men have a standard deviation equal to 10 beats per minute. 2) In 1997, a survey of 880 households showed that 145 of them use e-mail. Use those sample results to test the claim that more than 15% of households use e-mail. Use a 0.05 significance level.
