You performed a study investigating the effects of time pressure on performance on a verbal task. you had participants complete an anagrams task, where they had to unscramble some scrambled words. half of the participants were told that they would have to rush in order to get the anagrams completed, and the other half were told that they should have plenty of time to solve them all. the dependent measure was the number of anagrams solved. what type of test would you perform to examine whether the independent variable had a significant effect on anagram performance?

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- 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. 3- 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 part b?
