Can someone please help with my psychological research problem

Resolved Question:

Can someone please help with my psychological research problem below:

A researcher studying developmental changes in intelligence conducted the following cross-sectional study. The Wechsler Adult Intelligence Scale (a reliable and valid test) was given to 20 people at each of the following ages: 20, 30, 40, 50, 60, and 70. These are the results:

Age, 20; IQ, 120
Age, 30; IQ, 110
Age, 40; IQ, 100
Age, 50; IQ, 95
Age, 60; IQ, 93
Age, 70; IQ, 89

From these results the researcher concluded that intelligence peaks in the early years and declines steadily thereafter.

Do you agree with the researcher's conclusion? Why or why not?
