a) State the appropriate null and alternative hypotheses.
A college entrance exam company determined that a score of 22 on the mathematics portion of the exam suggests that a student is ready for college-level mathematics. To achieve this goal, the company recommends that students take a core curriculum of math courses in high school. Suppose a random sample of 150 students who completed this core set of courses results in a mean math score of 22.4 on the college entrance exam with a standard deviation of 3.8. Do...

Do students tend to improve their Math SAT scores the second time they take the test? We take a random sample of 100 hundred students who took the test twice. The mean score and the standard deviation of these 100 students on the first try are 500 and 90 respectively; the mean score and the standard deviation of these 100 students on the second try are 530 and 92 respectively. We also examine the change in Math SAT score (second...

It appears that sons of fathers who display low self-esteem tend to develop low self-esteem as well. Kuya conducted a study to test this hypothesis, since he is pretty sure that there must be a difference between the two groups, with sons having higher self-esteem than their fathers. He measured the self-esteem of the fathers and their sons using the Fearful Insecure Neurotic Emotional (FINE) test. The higher the score, the lower is the self-esteem. Is there a significant difference?...
