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 <em><u>correct answer</u></em> 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.

(Urgent) Solve: <br> z/4 + 5 ≥ 5.5
Olin [163]

z/4 + 5 >= 5.5

     -5       -5      subtract 5 from both sides

z/4       >= 0.5  

x4              x4    times both sides by 4

z          >= 2.0
