SAT Math scores are normally distributed with a mean of 500 and a standard deviation of 100. A sample of 90 test-takers is taken. What is the mean of the resulting sampling distribution of sample means of SAT scores? What is the standard error of the sampling distribution? Round to 2 decimal places. What is the probability that the sample will have a sample mean that is higher than an SAT Math score of 525? z-score: SAT Math score:

Step 1
Given that the mean of the population is 500 and the sample size is 90, the mean of the sampling distribution of sample means is the same as the population mean. Mean of the sampling distribution = 500 Show more…

The population of all test takers; SAT-Math scores have a mean of 500 and standard deviation of 100. If we were to repeatedly take samples of size 50 and record the sample means, what would we expect the mean of the distribution of sample means to equal?

SAT Scores SAT test scores are normally distributed with a mean of 500 and a standard deviation of 100 . Find the probability that a randomly chosen test-taker will score 650 or higher.

The SAT again High school students who take the SAT Math exam a second time generally score higher than on their first try. Past data suggest that the score increase has a standard deviation of about 50 points. How large a sample of high school students would be needed to estimate the mean change in SAT score to within 2 points with 95% confidence? Show your work.
