Scores for the verbal portion of the SAT-I test are
normally distributed with a mean of 509
and a standard deviation of 112. Randomly selected men
are given the Columbia Review
Course before taking the SAT test. Assume that the
course has no effect.

1. Suppose the scores for high school seniors on the verbal portion of the SAT test have a population mean of 509 and a population standard deviation of 112. a. List the population and the variable. b. What do you know about the population distribution of SAT scores for high school seniors? (i.e. shape, center, spread) c. Suppose we randomly select 56 high school seniors from this population. What would you expect the shape, mean and standard deviation of the...

The combined SAT scores for students taking the SAT-I test are normally distributed with a mean of 982 and a standard deviation of 192. Explain specifically why we could use the Central Limit Theorem to find the probability that a randomly selected sample of 9 students who took the SAT-I has a mean score between 800-1150 even though the same size is less than 30

Suppose that the population of SAT scores is normally distributed with a mean of 1000 and a standard deviation of 100. To determine the effect of a course to prepare for the SAT, a random sample of 25 students who have taken the course is selected. The sample mean SAT is 1050. Do these data provide sufficient evidence at the 1% significance level to infer that students who take the course perform better on the SAT on average? Assume that...
