Ziggy’s Circus charges a mean base price of $28 a ticket. In addition, the circus has additional charges for purchasing tickets online (as opposed to at the box office), sitting in the VIP section, and for concessions at the show. These additional charges average $13 per person. Suppose a random sample of 50 people attending the circus is taken to determine the total cost for a person attending the circus. Note the population standard deviation of total cost of attending is known to be $16 per person. Let LaTeX: \overline{x}=x ¯ =$41 . What is the probability the sample mean will be within $4 of the population mean cost of attending?

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?
