Scores on the Mathematics section of the SAT Reasoning Test form a normal distribution with a mean of μ = 500 and a standard deviation of σ = 100.
- a. If the state college only accepts students who score in the lop 60% on this test, what is the minimum score needed for admission?
- b. What is the minimum score necessary to be in the lop 10% of the distribution?
- c. What scores form the boundaries for the middle 50% of the distribution?
(a)
To find: What is the minimum score needed for admission.
Calculation:
The formula for z score is,
Substitute the value 500 for
(b)
To find: The minimum score needed for admission.
(c)
To find: The scores from the boundaries for the middle 50% of the distribution.
