Question

For all U.S. students nationally who take the SAT, SAT Math scores are normally distributed with an average score of 500 for all U.S. students and a population standard deviation of 125. A random sample of 100 students entering Whitmer College had an average SAT Math (SAT-M) score of 530.

*The sample data can be used* *to test the claim that
the mean SAT-M score of all Whitmer College students is different
than the national mean SAT-M score.*

*From the provided answer choices below, select the
appropriate null and alternate hypotheses:*

Answer #1

claim that the mean SAT-M score of all Whitmer College students is different than the national mean SAT-M score.

Claim = mean = = 500

Sample mean = = 530

Standard deviation = = 125

Null hypothesis: The mean SAT-M score of all Whitmer College students is 500

Alternate hypothesis: The mean SAT-M score of all Whitmer College students is different than 500

For all U.S. students nationally who take the SAT, SAT Math
scores are normally distributed with an average score of 500 for
all U.S. students . A random sample of 100 students entering
Whitmer College had an average SAT Math (SAT-M) score of 475 and a
sample standard deviation of 120. The sample data can be used to
test the claim that the mean SAT-M score of all Whitmer College
students is lower than the national mean SAT-M score. Based...

Math SAT: The math SAT test was originally
designed to have a mean of 500 and a standard deviation of 100. The
mean math SAT score last year was 515 but the standard deviation
was not reported. You read in an article for an SAT prep course
that states in a sample of 87 students, the mean math score was
534, but they did not disclose the standard deviation. Assume the
population standard deviation (σ) for all prep course
students...
