Question

According to Food Consumption, Prices, and Expenditures, published by the U.S. Department of Agriculture, the mean consumption of beef per person in the year 2000 was 64 lbs. (boneless, trimmed weight). A sample of 40 people taken this year yielded the data provided in the attached data file named Assessment 10 Data. Analyze the data to answer the following question. 1. Construct an appropriate graph of the provided data. Someone has claimed that there are outliers in the data set. Is this true? 2. Two colleagues argue whether to include or exclude the outliers. Person A claims that if we are interested in learning how much meat is eaten by people who eat meat, the outliers should be omitted. Person B claims that if we want to learn how much meat is eaten on average by Americans, we much include Americans who might be vegetarians. 3. A point estimate of the mean meat consumption is? 4. Does the 95% Confidence Interval for the Mean contain the hypothesized value of 64.0? 5. What is the p-value associated with the hypothesis test of μ = 64 using α=0.05? 6. Should you reject the null hypothesis that the mean meat consumption is 64 lbs.? 7. Suppose the true meat consumption was 58 lbs. Calculate the power of the hypothesis test you just completed (e.g., the probability of rejecting the null hypothesis that μ=64 given the true mean is 58) 8. In general, as the sample size increases the power
