Sam was given a bag of 100 red and blue marbles. He believes
that half of the marbles are red. To test his hypothesis, Sam
draws a marble from the bag without looking, records its color,
and then returns it to the bag. He repeats this process 49 times.
If Sam picks 35 blue and 15 red marbles, which conclusion is
accurate?
Select one:
There are probably more red marbles than blue marbles in the bag.
The number of red and blue marbles is probably the same.
There are probably only 15 red marbles in the bag.
There are probably more blue marbles than red marbles in the bag.

The ratio of blue marbles to red marbles is 35:15. To test his hypothesis in the best way, he should make sure that the total number of marbles he draws is 100. In other words, both sides of the ratio added together should equal 100. Right now, both sides equal 50 (35 + 15 = 50). To get to 100, double both sides of the ratio. Now, the ratio is 70:30. Based on the 50 marbles Sam drew, there are 70 blue marbles and 30 red marbles, meaning Sam's hypothesis is incorrect, and there are more blue marbles than red.
