1. Computer Exercise C3 For this exercise you will be using a variation of MEAPO1, which is cross-sectional school attainment data containing information on 4th-grade math scores ( math 4 ), 4th-grade reading scores ( read 4 ), expenditures per pupil ( exppp ), and other variables gathered from survey respondents for the state of Michigan in the year 2001. The following section gives detailed information about the variables within the data set: VARIABLE DESCRIPTIONS dcode = district code bcode = building code math 4 = percentage of students scoring at least satisfactory on their 4th grade math test read 4 = percentage of students scoring at least satisfactory on their 4th grade reading test lunch = percentage of students eligible for a free or reduced-cost lunch enroll = number of students enrolled at the school expend = total spending, in dollars exppp = expenditures per student: It enroll . in dollars lenroll = log (enroll) (1) The smallest value of math 4 is % , while the largest value of math 4 is % The range of minimum and maximum pass rate values is feasible because: both the minimum and maximum values are between 0% and 100%. both the minimum and maximum values are greater than 0%. the minimum value is greater than 0%. the maximum value is less than 100%. (ii) schools have a perfect pass rate on the math test. The number of schools that have a perfect pass rate on the math test represent of the total sample. (iii) schools have math pass rates of exactly 50%
