A mathematics professor gives two different tests to two sections of his college algebra classes. Assume the scores for both classes are normally distributed. The first class has a mean score of 56 with a standard deviation of 9 while the second has a mean score of 75 with a standard deviation of 15. A student from the first class scores a 62 on the test while a student from the second class scores an 83 on the test. Sketch each distribution and then compare the students’ scores.

Step 1
First, we need to sketch the normal distributions for both classes. Class 1: - Mean (μ1) = 56 - Standard Deviation (σ1) = 9 Class 2: - Mean (μ2) = 75 - Standard Deviation (σ2) = 15 Show more…

The scores from the first test for students in my statistics class have an average of 70 and a standard deviation of 3. The scores from the second test have the same average and standard deviation as the scores from the first test. The variance of the scores from the second test, given that the score on the first test is 65, is 2. Assume the scores of the students on the first test and second test are positively correlated and have a bivariate normal distribution. Calculate the average scores of the students on the second test, given that the scores on the first test are 65.

A math teacher gives two different tests to measure students' aptitude for math. Scores on the first test are normally distributed with a mean of 23 and a standard deviation of 5.1. Scores on the second test are normally distributed with a mean of 68 and a standard deviation of 10.4. Assume that the two tests use different scales to measure the same aptitude. If a student scores 28 on the first test, what would be his equivalent score on the second test? (That is, find the score that would put him in the same percentile.)
