Qui-Square Hypothesis Tests
Ramos has a spinning wheel. This spinning wheel has 18 blue numbers,
18 white numbers., and 2 yellow numbers. The table provided shows the
frequency with which the ball landed on each color in 200 trials.

At the 5% significance level, do the data suggest that the wheel is out of
balance? (You will need to compute the expected counts to do your
calculations, remember that the expected counts can be computed with the
formula E = np, where n is the number of trials and p is the probability of e
color).
