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 21.3 and the standard deviation was 5.1. identify the test scores that are significantly low or significantly high. what test scores are significantly low? select the correct answer below and fill in the answer box(es) to complete your choice. a. test scores that are between nothing and nothing. (round to one decimal place as needed. use ascending order.) b. test scores that are less than nothing. (round to one decimal place as needed.) c. test scores that are greater than nothing. (round to one decimal place as needed.)

The significantly low scores are those that are less than 11.1.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean and standard deviation , the zscore of a measure X is given by

In this problem, we have that:

In a recent year, the mean test score was 21.3 and the standard deviation was 5.1. This means that .

Consider a value to be significantly low if its z score less than or equal to -2;

The significant low scores are between 0 and X when . So these scores are the ones that are less than X when .

The significantly low scores are those that are less than 11.1.
