Consider a value to be significantly low if its z score less than or equal to minus2 or consider a value to be significantly high if its z score is greater than or equal to 2. a test is used to assess readiness for college. in a recent year, the mean test score was 22.1 and the standard deviation was 5.1. identify the test scores that are significantly low or significantly high.

A score of 11.9 or less will be considered significantly low.

A score of 32.3 or more will be considered significantly high.

Step-by-step explanation:

We are given the following in the question:

Mean, μ = 22.1

Standard Deviation, σ = 5.1

Formula:

a)  z score less than or equal to -2

Thus, a score of 11.9 or less will be considered significantly low.

b)  z score less than or equal to 2

Thus, a score of 32.3 or more will be considered significantly high.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
