Suppose 90% of a sample of 100 randomly selected homes in Town A and 80% of a sample of 50 randomly selected homes in Town B rely on the public water supply for drinking water. Compute the test statistic for a hypothesis test to compare the population proportion of homes that rely on the public water supply for drinking water in Town A to the proportion in Town B. Assume that the conditions for a hypothesis test for the difference between the population proportions are met. Round your answer to two decimal places.

A sample of 100 randomly selected oranda goldfish has a mean length of 6.75 inches. Suppose it is known that the population standard deviation of lengths of orandas is 0.985 inches. Use a 0.05 significance level to test the claim that the mean length of an oranda is greater than 6.65 inches. Fill in the following information as you test the above claim: State the claim symbolically and the opposite of the claim. H0: h1: Teststatistic: P-value: Conclusion:
