A math department gives all college algebra students a test to test rather or not students taking college algebra on site perform better on Final than students that take class completely online. The Math department gathers random samples of 40 on-site students (Students who take class in the classroom) and 35 online students. The test score for each student in the random sample is determined. The mean score for the on-site students is 75, with a standard deviation of 12....

Problem 2. Test Scores Distribution. In a certain exam is taken by 200 students, the average score was 60 out of maximum of 100 points. It was also found that 32 students scored more than 75 points. Assuming that the exam scores were well represented by a Gaussian probability density function, (2a) Determine the mean of the distribution. (2b) Determine the standard deviation of the distribution. (2c) Determine the number of students who scored more than 90 points. (2d) Determine...

The College Board finds that the distribution of students' SAT scores depends on the level of education their parents have. Children of parents who did not finish high school have SAT math scores X with mean 446 and standard deviation 103. Scores Y of children of parents with graduate degrees have mean 555 and standard deviation 107. Perhaps we should standardize to a common scale for equity. Find numbers a, b, c, and d such that a + bX and...
