According to the U.S. Golf Association (USGA), The weight of the [golf] ball shall not be greater
Question:
a. What assumptions must be made and what information must be known in order to use the binomial probability distribution to calculate the probability that the USGA will remove a particular kind of golf ball from its approved-ball list?
b. Suppose 10% of all balls produced by a particular manufacturer are less than 1.680 inches in diameter, and assume that the number of such balls, x, in a sample of two dozen balls can be adequately characterized by a binomial probability distribution. Find the mean and standard deviation of the binomial distribution.
c. Refer to part b. If x has a binomial distribution, then so does the number, y, of balls in the sample that meet the USGA's minimum diameter. [x + y = 24.] Describe the distribution of y. In particular, what are p, q, and n? Also, find E(y) and the standard deviation of y. Distribution
The word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
