Does this provide convincing evidence that seniors at Garfield High School study more than the report
stated?
A study reported that about half of high school seniors
study for upcoming math tests. To find out if this applies
to seniors at Garfield High School, an SRS of 30
seniors was asked if they study for their math tests.
Nineteen responded "Yes."
A dotplot is provided showing the results of 40 trials of
this simulation
No, there is an outlier at 20.
No, there were outcomes as low as 12.
Yes, only one trial had a result of 19 or larger
Yes, more than half of the simulated results are over
15.
Seniors Who Study for Math Tests

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?
