Answer:
<u>The correct answer is C. 20.33%</u>
Step-by-step explanation:
1. Let's review all the information given to us to answer the question correctly.
Mean of time of adults walking a mile = 22 minutes
Standard deviation = 6 minutes
Normal distribution for the walking times
2. What percentage of adults take longer than 27 minutes to walk a mile?
27 minutes = Mean + 5 minutes
27 minutes = Mean + 0.83 * Standard deviation
Using the z table for z = 0.83, we have that:
P (z) = 0.7967
Therefore the probability of adults that take longer than 27 minutes walking a mile is:
1 - 0.7967 = 0.2033
<u>The correct answer is C. 20.33%</u>
