Answer:
yes
Step-by-step explanation:
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).
It is B.
You see that the line segment crosses the y-axis at 1? That is known as the y intercept.
Remember y = mx + b?
Well in this graph, b = 1
Therefore it is B
Mode: 43 & 81 ( They both appeared the most amount of times)
Range: 41 (Subtract the largest number with the smallest number)
Mean: 58
Min: 40 (Q1)
Max: 81 (Q3)
Med: 54 (Q2)
