Which Z value would be used in calculating the following confidence levels? a. 50% b. 75% c. 66% d. 92% You own a restaurant, and part of your responsibilities include ordering enough food products for the week. To avoid ordering too little and missing out on profits, and ordering too much and throwing away food, you decide to track patterns in the dishes ordered in your restaurant. Your goal is to estimate about how much (a) chicken and (b) ground beef patrons order in a given week. After randomly tracking 20 weeks of orders, you find the following: For chicken, patrons ordered an average of 2,000lbs per week, with an SD of 700lbs For beef, patrons ordered an average of 3,000lbs per week, with an SD of 450lbs 2. Calculate the standard error of the mean for chicken in the sampling distribution 3. What Z-score should be used to construct a 90% confidence interval? 4. Construct a 90% confidence interval for average chicken consumed per week: (a) lower CI, (b) upper CI 5. Calculate the standard error of the mean for beef in the sampling distribution 6. What Z-score should be used to construct an 80% confidence interval? 7. Construct an 80% confidence interval for average beef consumed per week: (a) lower CI, (b) upper C ces arch a 29F 19516404 4:02 PM O 199+ W 2/24/2022 hp
