D E F
< 3/5 > mi-Assignment 8 - 4.1-4.4 Set background Clear frame 4.2 2) Minnesota's Best High School found that last year they did not have enough seats or room for all of the family members who wished to attend the graduation ceremony. The administrators at MBHS need to decide where to hold the graduation ceremony this year, so they sent a questionnaire home with each of this year's 543 seniors early in September. They asked for the surveys to be completed and returned by September 27th. Of the 148 surveys returned, the average number of seats that will be needed is 6.2. To be safe, the administrators use 7 and determine that they will need a hall that can hold 3800 people (543 students X 7 seats = 3801 seats needed) Using this number they find an appropriately sized hall and reserve it. Identify each of the following as specifically as possible: a) Population (of interest) b) Parameter (of interest) c) Sample d) Statistic e) Sampling method that was used? f) What is the response rate (the percent of surveys returned)? g) What is wrong with what these administrators have done? What type of bias or error is likely present?
