There is a 90 percent tendency that the average weight of a student in the class falls with 110 and 130 pounds.

Explanation:

Since precision rate is 10 pounds with a reliable accuracy rate of 90 percent. Then it will be a plus or minus 10 considering a sample estimate of 120 = plus or minus (120+10 or 120-10).
