Answer:
If the test is reliable, when Coleman retakes the same test at age 50 his score will likely still be 110.
Step-by-step explanation:
A test counts as reliable when it's consistent about measuring a certain characteristic. This means that if the individual takes the same test multiple times, he/she will likely get the same score as he/she did the first time.
In this case, if the Wechsler Adult Intelligence Scale test is reliable, Coleman will get the same score (110) when he is 50.
