two standardized tests,A and B, use very different scales of scores.the formula A=30×B +200 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 =17, Q3=32, mean=29, median=27, standard deviation =2 and IQR=5. find the summary statistics for equivalent scores on test A. Lowest score, mean, median,Q3, and IQR.

Two standardized tests, test A and test B, use very different scales. Assume that in one year the distribution of scores on test A can be modeled by N(1300,250) and scores on test B can be modeled by N(15, 3). If an applicant to a university has taken test A and scored 1670 and another student has taken test B and scored 19, compare these students' scores using z-values. Which one has a higher relative score? Explain. The Z-value of...

Professor Blockhus gives two different statistics tests, but one test is harder than the other. Scores on test A are normally distributed with a mean score of 78 and a standard deviation of 6. Scores on test B are also normally distributed but with a mean score of 65 and a standard deviation of 9. If Erik scored an 79 on test B, what percent of the class scored below him? That is, what is his percentile on test B.
Two standardized tests, test A and test B, use very different scales. Assume that in one year the distribution of scores on test A can be modeled by N(1300,250) and scores on test B can be modeled by N(15, 3). If an applicant to a university has taken test A and scored 1670 and another student has taken test B and scored 19, compare these students' scores using z-values.
