Prоf Reа's Exаm Q12 A rоulette wheel hаs 18 red numbers, 18 black numbers, and 2 green numbers. Sо, the proportion of red numbers is 0.474, the proportion of black numbers is 0.474, and the proportion of green numbers is 0.052. The table below gives the frequencies with which the ball landed on each color in 200 trials. Do the results suggest that the wheel is out of balance? Perform a goodness of fit test using a 5% level of significance. Step 1: Form your hypotheses. Step 2: Calculate the expected frequencies and verify that the criteria for the Chi-Square distribution is satisfied. Color Observed frequency Expected frequency red 84 black 106 green 10 Step 3: Calculate the test statistic. Round each term to four decimal places. Use the test statistic to find the P-value rounded to four decimal places. You may use this desmos graph to compute the P-value. Step 4: State the conclusion in the context of the problem.
