Answer:
According to the Empirical Rule, 68% of the data should fall between 11.98 and 18.02
Step-by-step explanation:
We are given the following data in the question:
10, 11, 12, 13, 13, 13, 14, 15, 16, 16, 17, 18, 18, 19, 20
Formula:
where are data points,
is the mean and n is the number of observations.
Sum of squares of differences = 25 + 16 + 9 + 4 + 4+ 4 + 1 + 0+ 1+ 1 + 4 + 9 + 9+ 16 + 25 = 128
Empirical rule:
- According to this rule almost all the data lies within three standard deviation of the mean for a normal distribution.
- About 68% of data lies within one standard deviation of the mean.
- About 95% of data lies within two standard deviations of mean.
- Arround 99.7% of data lies within three standard deviation of mean.
Thus, by empirical rule,
According to the Empirical Rule, 68% of the data should fall between 11.98 and 18.02
Answer:
Approximate volume of ice cream = 3.03 inches
Step-by-step explanation:
Given - An empty ice cream cone has a height of 3.02 inches and a radius
of 0.98 inches.
To find - What is the approximate volume of ice cream it will hold within the cone ?
Proof -
We know that,
Volume of the cone =
where
r is the radius of the cone
h is the height of the cone
Here,
Given that,
r = 0.98 inches
h = 3.02 inches
So,
Volume =
= ( Consider the value of
= 3.14)
= 3.0373
∴ we get
Approximate volume of ice cream = 3.03 inches
So,
The correct option is - G. 3 in 3
