You are the newly appointed assistant administrator at a local hospital, and your first project is to investigate the quality of the patient meals put out by the food-service department. You conducted a 10-day survey by submitting a simple questionnaire to the 400 patients with each meal, asking that they simply check off that the meal was either satisfactory or unsatisfactory. For simplicity in this problem, assume that the response was 1,000 returned questionnaires from the 1,200 meals each day. The results are as follows: NUMBER OF UNSATISFACTORY MEALS 42 SAMPLE SIZE 1,000 1,000 1,000 1,000 1,000 1,000 1,000 1,000 1,000 1,000 December 1 December 2 47 63 December 3 December 4 December 5 December 6 48 60 62 43 62 December 7 December 8 December 9 66 December 10 53 [s23)] 10,000 a. Determine the p, Sp, UCL and LCL based on the questionnaire results, using a confidence interval of 95.5 percent, which is two standard deviations. (Round your answers to 4 decimal places.) .0546 Sp UCL LCL

Translate each of the following research questions into appropriate H0 and Ha. Census Bureau data show that the mean household income in the area served by a shopping mall is $42,800 per year. A market research firm questions shoppers at the mall to find out whether the mean household income of mall shoppers is higher than that of the general population. Last year, your online registration technicians took an average of 0.4 hours to respond to trouble calls from students trying to register. Do this year’s data show a different average response time?
You are now the administrator of a local hospital, and your first project is to research the quality of meals for patients prepared by the food service department.To do this, he conducted a survey for 10 days presenting a simple questionnaire to 400 patients with each meal, asking them to mark whether the meal had been satisfactory or unsatisfactory.For simplicity in this problem, suppose the response was 1,000 questionnaires returned from 1,200 meals each day.The results are the following: Sample sample size Number of unsatisfactory foods dic-01 1,000 74 dic-02 1,000 42 dic-03 1,000 64 dic-04 1,000 80 dic-05 1,000 40 dic-06 1,000 50 dic-07 1,000 65 dic-08 1,000 70 dic-09…

Use last digit of your student ID(I called it b) to do the following problem. Charges for advertising on a TV show are based on the number of viewers, which is measured by the rating. The rating is a percentage of the population of 110 million TV households. The CBS television show 60 Minutes recently had a rating of 7.8, indicating that 7.8% of the households were tuned to that show. An advertiser conducts an independent survey of 100 households and finds that only 6+1 were tuned to 60 Minutes. Assuming that the 7.8 rating is correct, find the probability of surveying 100 randomly selected households and getting 6+1 or fewer tuned to 60 Minutes. What does this suggest? Does the advertiser have grounds for claiming a refund on the basis that the size of the audience was exaggerated?
As the newly hired manager of a company that provides cell phone service, you want to determine the percentage of adults in your state who live in a household with cellphones and no land-line phones. How many adults must you survey? Assume that you want to be 90% confident that the sample percentage is within four percentage points of the true population percentage.Assume that nothing is known about the percentage of adults who live in a household with cell phones and no land-line phones. Solve the previous question if assuming that a recent survey suggests that about 92% of adults live in a household with cell phones and no land-line phones (based on data from a survey).
A group of 100 people, who lived at varying distances (in kilometers) from an island nuclear power station, were asked if they thought a full evacuation of the area was required, when it went critical. The researches wanted to know if the opinion to evacuate or not depended on how far from the reactor people lived. Partial results of the questionnaire are shown in the table below. 0-3 km distance 3 -6 km distance 6 -9 km distance 9- 12 km distance Totals Evacuation needed X X X 51 Evacuation not X X XX needed Totals 28 28 23 XX XX You are doing a Chi Square test for independence. What is the expected value of the number of people living within a radius of 0-3 km who would say that evacuation was needed? XX denotes row/column totals. Give your answer to 2 decimal places.
