Round your answer to four decimal places.P(x=7)=P(x=7)= Find the probability of 7 or fewer Mexican-Americans among 12 jurors. Round your answer to four decimal places.P(x≤7)=P(x≤7)= Does 7 Mexican-Americans among 12 jurors suggest that the selection process discriminates against Mexican-Americans? no yes
Suppose that you will roll 2, fair 6-sided dice (assume a Laplace probability model). Afterwards, you will: (a) Double the result of the first roll. (b) Double the result of the second roll. (c) Sum together the results that you get in (a) and (b). Make a prediction for the value that you will end up getting in (c), and enter it below.

Which of the following is not a property of a discrete probability distribution being valid? All values of P(x) must be positive. All values of P(x) must fall between 0 and 1. All values of x must be positive. The sum of all P(x) values must be 1.
Flat screen TVs require high quality glass with very few flaws. A television manufacturer receives glass panels from two different suppliers. Let x and y denote the number of flaws in a randomly selected glass panel from the first and second suppliers, respectively. Suppose that the probability distributions for x and y are as follows. 1 2 3 4 p(x) 0.4 0.3 0.2 0.1 y 1 2 3 4 P(y) 0.2 0.6 0.2 The mean values of both x and y are 1. However, the probability distribution for the second supplier is concentrated closer to the mean value than is the first supplier's distribution. If the manufacturer wanted to select a single supplier for glass panels, which of these two suppliers would you recommend? Justify your choice based on consideration of both center and variability. O The two suppliers are equal in terms of center, however the the greater variability in the first distribution tells us that it is more consistent. Thus the first supplier should be recommended. O The two suppliers are…
I need help with this:A manufacturer knows that on average 20% of toasters produced require repairs within 1 year after they are sold. When 18 toasters are randomly selected, find the smallest number x and largest number y such that (a) the probability that at least x of them will require repairs is less than 0.58; (b) the probability that at least y of them will not require repairs is greater than 0.84.
