Jen observed that 91% of the background checks he processes are for potential employees who have already interviewed. Let X be the number of background checks Jen processes to get his first background check for a potential employee who has not yet interviewed for the job. Assume that the interview statuses are independent.

(a) Find the probability that the 2nd background check that Jen processes is the first for which the potential employee has not yet interviewed.

(b) What is the underlying process for the random variable X?

(c) Suppose Y is the number of potential employees who have already interviewed in a group of 15 employees. How are X and Y different?

Background Numerous studies have shown that the intracellular redox potential of the cell is important to cell growth. Cellular redox potential can be determined by the amounts of the reduced coenzyme NADPH, a principal product of the oxidative branch of the pentose phosphate pathway (PPP). The investigators in the study presented here sought to demonstrate links between the activity of the enzyme glucose-6-phosphate dehydrogenase (G6PD) activity, cellular NADPH concentrations, and rates of cell growth. Previous studies have shown that the...

A child who gets into an elite preschool will have a lifetime earning potential given by a Poisson random variable with mean $3,310,000. If the child does not get into the preschool, her earning potential will be Poisson with mean $2,700,000. Let X = 1 if the child gets into the elite preschool, and zero otherwise, and assume that P(X = 1) = p. (a) Find the covariance of X and the child’s lifetime earnings. (b) Find the correlation of...
