You are driving home one night and must decide if you have enough gas to get home or not. Use the hypotheses below to answer the questions. Ho: My vehicle has enough gas to get home.Ha: My vehicle does not have enough gas to get home. A. A type I error occurs if I conclude (believe) my vehicle does/does not (circle the correct choice) have enough gas to get home, but in fact, my vehicle does / does not (circle the correct choice)have enough gas to get home. B. List one possible consequence that could happen if you made a type I error. C. A type II error occurs if I conclude (believe) my vehicle does / does not (circle the correct choice ) have enough gas to get home, but in fact, my vehicle does / does not (circle the correct choice) have enough gas to get home. D. List one possible consequence that could happen if you made a type Il error. E. Based on the seriousness of the consequences of these two errors, we should set a / B to be less than a /B.

A researcher is interested in whether people are more or less likely to enjoy popcorn when they are watching TV versus watching a movie. The researcher recruits 12 participants and randomly assigns them to eat popcorn either while watching T or while watching a movie. Then, the researcher measures now much each participant enjoyed the popcorn on a scale from 1 to 10. The researchers' results are shown below: Using the appropriate hypothesis test and the six steps of hypothesis testing, see what the researcher should conclude about the effect of watching television versus watching a movie on people's enjoyment of popcorn. 1. What is the appropriate test to use ? 2. List the test's assumptions You do NOT have to test the assumptions. 3. What are the null and alternative hypotheses ? 4. Construct a sampling distribution of means representing the null hypothesis. Specify the sampling distribution's mean and standard error 5. Using a two-tailed alpha of .05 (a = .05), determine the…

Describe type I and type Il errors for a hypothesis test of the indicated claim. A furniture store claims that no more than 60% of its new customers will return to buy their next piece of furniture. Describe the type error. Choose the correct answer below. A. A type error will occur when the actual proportion of new customers who return to buy their next piece of furniture is no more than 0 60 but you reject Ho p≤0.60. B Atype error will occur when the actual proportion of new customers who return to buy their next piece of furniture is at least 0 60, but you reject H, p=0.60 C. A type l error will occur when the actual proportion of new customers who return to buy their next piece of furniture is at least 0.60, but you fail to reject H, p=0.60 D Atype 1 error will occur when the actual pro ortion of new customers who return to buy their next piece of furniture is Clear all Check answer
