Hypothesis Testing with the p-value Method 2. 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? (Adapted from American Automobile Association) 1.) Is this a hypothesis test for mean or proportion? If it's a test for mean, do we know the population standard deviation? IN 2.) Based on your answer in #1, which calculator will you use: 4 A.) Mean - o Known, B.) Mean - o Unknown or C.) Proportions 15 16 3.) Will we use a Z-test or t-test? How do you know? 18 19 20 21 4.) What is the direction of the tail? Left, right or two? 22 23 24 25 5.) Complete the Hypothesis statement below with the arrows in the correct direction. Mark an X next to the claim. 26 27 28 29 Claim 30 Null Ho: (Use u for mean and p for proportion) 31 Alternative Ha: 32 33 Complete the correct calculator with the values from the problem. 34 35 6.) Compare the p-value with the level of signficiance. Is the p-value less than or greater than alpha? 36 37 20 7.) Based on your answer in #6, do we reject or fail to reject the null Ho
