There are two math teachers at Delta College who are at odds about pedagogy. One teacher (teacher A) claims that the traditional way of teaching math is better. Teacher A’s students had a mean score of 473 with a standard deviation of 35. This teacher had 12 students take the placement test. Teacher B’s students had a mean score of 450 with a standard deviation of 40. This teacher had 15 students take the test. Can you conclude that the traditional way is better? Assume that the populations are normal and that the variances are not equal (not pooled).

6. 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 4. Scores on the second test are normally distributed with a mean of 64 and a standard deviation of 10. Assume that the two tests use different scales to measure the same aptitude. If a student scores 29 on the first test, what would be his equivalent score...

A 6th grade teacher was interested in comparing two ways of teaching math to her students. She used method A with one of her existing classes and method B with another one. She flipped a coin to decide which class would receive method A. At the end of the year her students obtained the following scores (percent correct) on a comprehensive math exam. Method A: 75, 82, 88, 93, 69, 72, 78, 81, 84, 96 Method B: 66, 84, 72,...
