26. Using the binomial distribution the probability that a sample of n = 10 from a process with proportion defective p = 0.1 will gives exactly one defective item is:
a. 0.1 b. 0.3874 c. 0.7361 d. 0.3588
Homework Answers
p = 0.1 => q = 1-p = 0.9; r= 9 and n= 10
P(Defective =1) = nCr*pn-r*qr = 10C9*(0.1)*(0.9)9= 0.3874

Lesson 6.2.4: Binomial Distribution and Sample Proportions A sample proportion, such as the one computed in Question 4, is equal to a number of successes (x), divided by the sample size (n). The notation for a sample proportion is p, and it is computed by the formula p = Each value of x corresponds to a unique sample proportion ( p ), as computed by this formula. For example, x = 1 implies p = + - 0.10. These events,...
