(b) 20.100 = 1.282 Based on your sample, graph the 95% confidence interval for the population proportion of all winning scratchers. • Enter the values for the lower and upper limits on the graph to show your confidence interval. For the point (+), enter the claim 0.42 from the advertisement. 0.000 0.000 95% confidence interval: 0.500 (c) Does the 95% confidence interval you constructed contradict the claim from the advertisement? Choose the best answer from the choices below. Check Espar 1.000 00 E ΠΡ 1.000 O No, the confidence interval does not contradict the claim. The proportion 0.42 from the advertisement is inside the 95% confidence interval. No, the confidence interval does not contradict the claim. The proportion 0.42 from the advertisement is outside the 95% confidence interval. O Yes, the confidence interval contradicts the claim. The proportion 0.42 from the advertisement is inside the 95% confidence interval. Yes, the confidence interval contradicts the claim.

An advertisement for this lottery claims that 42% of the population of all the scratchers are winning ones. You want to research this claim by selecting a random sample of 48 scratchers. Follow the steps below to construct a 95% confidence interval for the population proportion of all winning scratchers. Then state whether the confidence interval you construct contradicts the advertisement's claim. (If necessary, consult a list of formulas.)
