A survey is planned to estimate the proportion of voters who support a proposed gun control law. The estimate should be within a margin of error of with 90% confidence, and we do not have any prior knowledge about the proportion who might support the law. How many people need to be included in the sample

![n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p )](/tpl/images/0866/6927/c7923.png)
![n = [\frac{1.645 }{0.05} ]^2 * 0.5 (1 - 0.5 )](/tpl/images/0866/6927/14777.png)

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?
