Question:

The panels for the Pulsar 32-inch widescreen LCD HDTVs in a production run were checked by examining samples of 6. The following table shows the number of defective panels contained in a distribution of 30 samples.

Number of Defectives in Sample 0 1 2 3 4 or more
Number of Samples 24 3 2 1 0

a. Find the mean number of defective panels per sample. (Round your answer to three decimal places.)

b. Assuming that the distribution is binomial, estimate the percentage of defective panels in the production run. (Round your answer to one decimal place.)

Probability and Expectation:

The probability distribution of a discrete random variable X expresses the probabilities of all the possible outcomes of X. The expected value of X is calculated using the formula:

{eq}E(X) = \sum xP(X = x) {/eq}

Answer and Explanation:


Given Information:

The following table shows the number of defective panels contained in a distribution of 30 samples:
