Question

Many companies use a quality control technique called acceptance sampling to monitor incoming shipments of parts, raw materials, and so on. In the electronics industry, component parts are commonly shipped from suppliers in large lots. Inspection of a sample of 40 components can be viewed as the 40 trials of a binomial experiment. The outcome for each component tested (trial) will be that the component is classified as good or defective. Reynolds Electronics accepts a lot from a particular supplier if the defective components in the lot do not exceed 5%. Suppose a random sample of five items from a recent shipment is tested. Assume that 5% of the shipment is defective and this probability do not change from trial to trial (follows a binomial distribution). What is the probability that one item in the sample are defective. (Use four decimal accuracy for your intermediate and final answer calculations) Question 1 options: 0.4705 0.3856 0.5646 0.2706

(please show in excel)

Answer #1

Binomial probability is given by

P(X=x) = C(n,x)*p^{x}*(1-p)^{(n-x)} |

where

Sample size , n = 40

Probability of an event of interest, p = 0.05

P ( X = 1 ) = C(
40 , 1 )*
0.05 ^ 1 *
0.950 ^ 39 =
**0.2706(answer)**

**excel formula: =BINOM.DIST(1 ,40, 0.05,
FALSE)**

**answer: = 0.2706**

An electronic component is produced in batches of 25 units.
Acceptance sampling is performed by the buyer to protect himself
from batches that come from a process with an unacceptable number
of defective components.
The sampling consists of the following:
From the batch of 25 units, 5 units are drawn at random, without
replacement, and their operation is tested.
If neither part fails, the lot is accepted.
If there were 2 defective units among the 25 pieces in the lot,...
