A company that produces an expensive stereo component is considering offering a warranty on the component. Suppose the populatio
Llana [10]

Answer:

Warranty of 66 months.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 84, \sigma = 9

If the company wants no more than 2% of the components to wear out before they reach the warranty date, what number of months should be used for the warranty?

Only the lowest 2% will be replaced, so the warranty is the value of X when Z has a pvalue of 0.02. So it is X when Z = -2.055.

Z = \frac{X - \mu}{\sigma}

-2.055 = \frac{X - 84}{9}

X - 84 = -2.055*9

X = 65.5

Warranty of 66 months.
