We denote by q1 the x-coordinate correponding to the red point and by q2 the x-coordinate corresponding to the blue point. Which of the following statements are true? 1.00 - 0.75 0.50 - 0.25+ 0.00 - The answer is : The cdf of X corresponds to the red curve while the one of Y corresponds to the blue curve.

French fries have numerous quality attributes that are important to customers. One of these is called "dark ends," which are the dark-colored ends that can occur when the fries are cooked. Suppose a major customer will accept no more than 0.09 of the fries having dark ends. une culter illaccept no mo Recently, the customer called the company saying that a recent random sample of 400 fries was tested from a shipment and 48 fries had dark ends. Assuming that the population does meet the 0.09 standard, what is the probability of getting a sample of 400 with 48 or more dark ends? Comment on this result. The probability of getting a sample of 400 with 48 or more dark ends is (Round to four decimal places as needed.)
