(B) Additional Problem: 1. For each of the following, no work is required, just determine which distribution is needed to find the probability, or other statistic, requested. Your answer only needs to reflect the letter indicated with the distribution that describes the situation, written on your other papers (this page will not be graded.) (D) Hypergeometric Distribution (E) Multivariable Hypergeometric Distribution (F) None of the Above (A) Discrete Uniform Distribution (B) Binomial Distribution (C) Multinomial Distribution (i) A package of eight batteries is opened and the tester checks each battery to see if it is dead or not. The company boasts that a single batter has a 3% chance of being dead in the package. The tester will keep track of the number of dead batteries in a given package.
