Scrapie is a degenerative disease of the nervous system. A study of the substance IDX as a treatment for scrapie used as subjects 20 infected hamsters. Ten, chosen at random, were injected with IDX. The other 10 were untreated. The researchers recorded how long each hamster lived. They reported: Thus, although all infected control hamsters had died by 92 days after infection (mean +_ SEM = 86.2 +_ 1.64), IDX-treated hamsters lived up to 110 days (mean +_ SEM = 100.9 +_ 2.78). Readers are supposed to know that SEM stands for the standard error of the mean.
(a) For the group injected with IDX, find:The mean, x^- r = The standard deviation, s = (b) For the untreated grop, find:The mean, x^- bar = The standard deviation, s =

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?
