The length of an instant message conversation is normally distributed with a mean of 5 minutes and a standard deviation of .7 mi

Charra [1.4K]

The correct answer is:

0.0764

Explanation:

We will use a z-score to answer this. The formula for a z-score is

$z=\frac{X-\mu}{\sigma}$ , where μ is the mean and σ is the standard deviation. Using our information in this problem, we have

$z=\frac{6-5}{0.7}=\frac{1}{0.7}=1.43$

Using a z-table, we look up the z-score 1.43. The area under the curve to the left of, or less than, this value is 0.9236. This means the probability that the time is greater than this is 1-0.9236 = 0.0764.
