Answer:
She should offer a guarantee of 6.24 years.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
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 = 10, \sigma = 2](https://tex.z-dn.net/?f=%5Cmu%20%3D%2010%2C%20%5Csigma%20%3D%202)
If she is willing to replace 3% of the motors that fail, how long a guarantee (in years) should she offer?
This is the value of X when Z has a pvalue of 0.03. So it is X when Z = -1.88. So
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
![-1.88 = \frac{X - 10}{2}](https://tex.z-dn.net/?f=-1.88%20%3D%20%5Cfrac%7BX%20-%2010%7D%7B2%7D)
![X - 10 = -1.88*2](https://tex.z-dn.net/?f=X%20-%2010%20%3D%20-1.88%2A2)
![X = 6.24](https://tex.z-dn.net/?f=X%20%3D%206.24)
She should offer a guarantee of 6.24 years.
