Explanation:
To find the percentage of cars averaged less than 62 mph calculate the corresponding z-score and use a standard normal cumulative probability table
<u>1. Z-score</u>
- x is the specific value of the random variable: 62mph
- μ is the mean of the population: 65mph
- σ is the standard deviation of the population: 5mph
Substitute and calculate
<u>2. Use of the table.</u>
The percentage of cars that averaged less than 62mph is given by the area under the curve to the left of z = -0.600.
From a standard normal cumulative probability table, the probability of z being less than -0.600 (which is equal to the probability of z being greater than 0.600) is 0.2743, which is 27.43%.
Thus, the conclusion is that 27.43% of the cars averaged less than 62mph.

As a teenager, "short term" may be a matter of a week or two. As a middle-aged adult, both your life-lived and life-expectancy are somwhat longer, so "short-term" can be somewhat longer as well. In old age and failing health, "short-term" may again be a matter of a few weeks at most. Such concepts are tempered by perspective.
