"A handgrip dynamometer is used to measure the maximum isometric strength of the hand and forearm muscles. The score for ten individuals are listed below separately for dominant and nondominant hand. A high score means a stronger grip. Assume dynamometer measurements are normally distributed for both dominant and non-dominant hands. At the 0.1 significance level, test the claim that on average an individual’s dominant hand is stronger than their non-dominant hand."

Estimate the product. round the first factor to the nearest whole number, round the second factor to the nearest ten, and then multiply. 3 8/9 × 96

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
