Two standardized tests, A and B, use very different scales of scores. The formula Upper A equals 40 times Upper B plus 50 approximates the relationship between scores on the two tests. Use the summary statistics for a sample of students who took test B to determine the summary statistics for equivalent scores on test A. Lowest score = 20. Mean = 26, Standard Deviation = 5
Q3 = 31, Median = 29, IQR = 7
