Answer:
(14, 22)
Explanation:
The amount of time that customers have to wait for their food is normally distributed with:
• Mean = 18 minutes
,
• Standard deviation = 4 minutes.
The Empirical Rule
For normal distributions, the empirical rule states that:
• 68% of observed data points will lie inside one standard deviation of the mean.
,
• 95% will fall within two standard deviations
,
• 99.7% will occur within three standard deviations.
By the empirical rule, 68% of observed data points will lie inside one standard deviation of the mean.
Therefore, the interval of minutes that the middle 68% of customers have to wait is:
The interval is (14, 22).
