The host, Monty Hall, would randomly select contestants from the audience and, as the title suggests, he would make deals for prizes. Contestants would be given relatively modest prizes and then would be offered the opportunity to risk that prize to win better ones. Suppose a contestant on this show, On the stage are three curtains, A, B, and C. Behind one of them is a brand-new car worth $45,000. Behind the other two curtains, the stage is empty.mthey must now select one of the curtains. Suppose you select Curtain A.In an attempt to make things more interesting, Monty then exposes an empty stage by opening Curtain C (note: he knows that there is nothing behind Curtain C). He then asks if they want to keep Curtain A, or switch to Curtain B.What should they do? Keep Curtain A or switch to Curtain B?arrow_forward

- The following table describes the probability distribution of the number of Mexican-Americans serving on a 12-member jury in Hidalgo County, Texas. Assuming we repeat the random selection process for the 12 jurors and count the number of Mexican-Americans each time, calculate the mean number of Mexican-Americans (out of 12), the variance, and the standard deviation. Use these results and the interval rule of thumb to calculate the highest common value and the lowest common value. Based on the results, determine whether a jury consisting of 7 Mexican-Americans out of 12 jurors is common or uncommon. Probability distribution: probabilities of numbers of Mexican-Americans on a 12-member jury, assuming the members are randomly selected from a population in which 80% of the inhabitants are Mexican-American x (méxico- estadouni- P(x) denses) 0 0+ 1 0+ 2 0+ 3 0+ 4 0.001 5 0.003 6 0.016 7 0.053 8 0.133 9 0.236 10 0.283 11 0.206 12 0.069arrow_forwarda) When two variables are correlated, can the researcher be sure that one variable causes the other?
