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 modelled by N(700, 75) and that of scores on test B can be modelled by N(21, 3). If an applicant to a university has taken test A and scored 840 and another student has taken test B and scored 27, compare these students' scores using z-values. Which one has a higher relative score? Explain. The z-value of the test A score is zA - (Round to two decimal places as needed.)
