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 520 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 different than the national mean SAT-M score. Based...

Adult intelligence scores are distributed approximately normally
with μ = 100 and σ =
15. Therefore, means of simple random samples of n intelligence
scores are distributed
approximately normally with with μ = 100 and σ = 15/Ön. In each
part of this question, carry out any
calculations using two places after the decimal point for z scores
and four places after the decimal point for
proportions.
a) What proportion of intelligence scores is lower than 94?
b) What proportion of...

The SAT scores for US high school students are normally
distributed with a mean of 1500 and a standard deviation of
100.
1. Calculate the probability that a randomly selected student
has a SAT score greater than 1650.
2. Calculate the probability that a randomly selected student
has a SAT score between 1400 and 1650, inclusive.
3. If we have random sample of 100 students, find the probability
that the mean scores between 1485 and 1510, inclusive.
