A lot of size N = 25 contains 5 nonconforming units. The testing procedure: if a sample of6 contains 1 or less nonconforming units, the lot is accepted.(a) What is the probability of lot acceptance?(b) Calculate the desired probability in (a) using binomial approximation? Is thisapproximation satisfactory? Why or why not?(c) Suppose the lot size was N = 300. Recalculate the probability (a) with binomialapproximation? Is this approximation satisfactory? Why or why not?

A business calculates that 60% of its suppliers are UK-based. Every month it randomly selects 8 of its suppliers and checks their compliance with money-laundering legislation. It defines the random variable X to represent how many of the 8 selected supplie are UK-based. This scenario is modelled with a Binomial distribution denoted X- Bin(n, p). (a) State the value of n (b) State the value of p, writing your answer as a decimal to 1 decimal place. (c) How many combinations of 5 UK-based suppliers are possible within the set of 8 suppliers selected for the compliance checks? (d) Calculate the probability that there are exactly 5 UK-based suppliers within the set of 8 suppliers selected for the compliance checks. Answer to 2 decimal places.

An aircraft seam requires 26 rivets. The seam will have to be reworked if any of these rivets is defective. Suppose rivets are defective independently of one another, each with the same probability. (Round your answers to four decimal places.) (a) If 24% of all seams need reworking, what is the probability that a rivet is defective? 0.010 X (b) How small should the probability of a defective rivet be to ensure that only 5% of all seams need reworking?
In the binomial probability distribution, let the number of trials be n = 4, and let the probability of success be p = 0.3553. Use a calculator to compute the following. (a) The probability of three successes. (Round your answer to three decimal places.)(b) The probability of four successes. (Round your answer to three decimal places.)(c) The probability of three or four successes. (Round your answer to three decimal places.)
In studies for a medication, 7 percent of patients gained weight as a side effect. Suppose 565 patients are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 40 patients will gain weight as a side effect. (b) no more than 40 patients will gain weight as a side effect. (c) at least 51 patients will gain weight as a side effect. What does this result suggest? (a) P(40) = (Round to four decimal places as needed) (b) P(X< 40) = (Round to four decimal places as needed) (c) P(X251) = (Round to four decimal places as needed) Since 51 is than 7% of the patients, this suggests that the proportion of patients that gain weight as a side effect is 0.07.
