QUESTION 2 In a survey performed at the University, it was found that 46 out of 446 students interviewed believed that race and racism is an important issue. If we want to construct a 90% confidence interval for the true proportion of students who believe that race and racism is an important issue, what would be the margin of error? (express the result in percentage and round to the nearest tenth). QUESTION 3 In...

Exercise 6. This problem describes an experiment in which conditional probabilities are used to compute "proper" probability. The experiment starts with two urns, Urn #1 contains 5 white marbles and 2 black marbles. Urn #2 contains 7 white marbles and 3 black marbles. One marble from each urn is drawn at random. (For each urn, the chance of each marble being drawn is the same.) Let T be the event that the two marbles are the same color. Let...
A card is drawn from a deck of 52 playing cards. Given that it is a black card, what is the probability that it is the following? (Enter your probabilities as fractions.) (a) a club (b) a jack A card is drawn from a deck of 52 playing cards. Find the following probabilities as fractions. Find the following probabilities. Pr(queen ∩ red) = Pr(red) = Pr(queen | red) = (b) Find the following probabilities. What is the probability that the...

7.4.19-T Question Help Compute P(x) using the binomial probability formula. Then determine whether the normal distribution can be used to estimate this probability. If so, approximate P(x) using the normal distribution and compare the result with the exact probability. n 72, p 0.81, and x 65 For n 72, p 0.81, and x 65, find P(x) using the binomial probability distribution P(x) 0.0148 (Round to four decimal places as needed.)
