A tourist agency in Nevada claims the mean daily cost of meals and lodging for 2 adults traveling in the state is more than $300. You work for a consumer protection advocate and want to test this claim. In a random sample of 35 pairs of adults traveling in Nevada, the mean daily cost of meals and lodging is $316. Assume the population standard deviation is $30. At a=0.10, do you have enough evidence to support the agency's claim?

1. Decide what kind of test you need to perform. In the blank below, type the correct letter for the corresponding test:

A. Mean test w/ z-score (large sample,
known)

B. Mean test w/ t-score (small sample,
unknown)

C. Proportion test w/ z-score

D. Difference test w/ z-score

2. Decide what kind of test you are performing (left-tailed, right-tailed, two-tailed). You can type your response in the blank below with one of your three options.

3. Calculate the appropriate critical value (z-score, t-score) for your test. Be sure to use the correct formula based on your answer in part 1 of this problem. Round your result to the nearest hundredth.

4. Use the appropriate chart to find either: a) a p-value based on your z-score, or b) a
based on your degrees of freedom & alpha value. Record your answer in the blank below. Round p-values to the fourth decimal place, and round
values to the third decimal place.
