A company claims that 80% of its customers are under 30. You suspect it is less than this. You take a random sample of 200 customers to test this and find out that 75% of your sample are under 30. What is the alternative hypothesis here? a. The proportion of customers under 30 is less than 75% b. The proportion of customers under 30 is less than 80% c. The proportion of customers under 30 is equal to 75%

What price do farmers get for their watermelon crops? In the third week of July, a random sample of 40 farming regions gave a sample mean of x = $6.88 per 100 pounds of watermelon. Assume that ? is known to be $1.92 per 100 pounds.

You gather data from two local churches about the average offering (a monetary donation to the church)that is collected at a weekly service. You want to see whether the average offering given at one churchis the same as the average offering at another church. The number of people who attend Church 1 is201, and the average amount offered is $12.50. The number of people who attend Church 2 is 350, andthe average amount offered is $11.87. The sample standard deviations for Church 1 and Church 2 are$3.15 and $4.57, respectively. (a) What is the hypothesis you want to test? (b) Calculate the test statistic and test your hypothesis at the 95 and 99 percent confidence levels. (c) Pretend that the sample means and standard deviations remain the same, but that the numberof people sampled at Church 2 was 201 instead of 350. Does your test-statistic change? Does the critical value change?

You are testing the claim that the proportion of men who own cats is smaller than the proportion of women who own cats.You sample 110 men, and 90% own cats.You sample 90 women, and 20% own cats.Find the proportion of the pooled samples, (pcpc), as a decimal, rounded to two decimal places.
Mary is running for mayor. She wants to know if she has a chance to win, so she collects a random sample of 40 citizens to see if they are going to vote for her of her opponent, Henry. Out of the 40 citizens who were asked, 24 said they were voting for Henry and the other 16 said they were voting for Mary. Using this data test H0: p=.5 vs. Ha: p>.5, where p is the true proportion of people, who will vote for Mary in the population (i.e., the entire town)? Find the p-value of this test, and what is your conclusion if the test is performed at the a=.5 level?
