(iv) The average pass rate for the math test is approximately , and the average pass rate for the reading test is approximately True or False: One of the possible reasons that explains the difference in the average pass rates for the math and reading tests in 2001 is that the math test was more difficult than than the reading test. True O False (v) The correlation between math 4 and read 4 is True or False: Schools that have low pass rates on one test have a strong tendency to have low pass rates on the other test. True O False (vi) The average expenditure per pupil for the schools in the sample is approximately , and the standard deviation is approximately One way to measure the spread of variation in per pupil spending is through the coefficient of variation (CV): CV = standard deviation where a CV > 1 indicates a relatively high spread of variation and a CV
