If a roulette wheel is properly balanced, the ball will land on red 18 out of 38 times or with probability 0.474. A gambler studies a roulette wheel to see if it is unbalanced and he can cheat. He observes 300 spins of the wheel and finds that the ball lands on red 147 times. At the 5% significance level, do the data provide sufficient evidence to conclude that the wheel is unbalanced? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: Select an answer Ha ? Select an answer c. The test statistic ? = d. The p-value = e. The p-value is ? a (please enter a decimal) (Please enter a decimal) (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) f. Based on this, we should Select an answer the null hypothesis. g. Thus, the final conclusion is that ... The data suggest the population proportion is not significantly different from 0.474 at a = 0.05, so there is sufficient evidence to conclude that the wheel is unbalanced. O The data suggest the population proportion is not significantly different from 0.474 at a = 0.05, so there is not sufficient evidence to conclude that the wheel is unbalanced. O The data suggest the populaton proportion is significantly different from 0.474 at a = 0.05, so there is sufficient evidence to conclude that the wheel is unbalanced.
