Transcribed Image Text:n= 50
Mean, =
ΣΧ
= 1570/50 = 31.4
Standard deviation, o =
= 20.41
Using empirical rule, 68% of the data falls within one standard deviation, 95% within two standard deviations,
and 99.7% within three standard deviations from the mean.
=> 68% of data falls between e + o = 31.4 + 20.41 = (10.99, 51.81)
=> 95% of the data falls between e ± 2 * o = 31.4 + 2*20.41 = (-9.42, 72.22)
=> 99.7% of the data falls between + 3 * o = 31.4 +3*20.41 = (-29.83, 92.63)
QUESTIONS:
1. How does answers in 68%, 95%, and 99.7% of data compare, respectively?
2. How does it support the conclusion you reached in question 1? Explain thoroughly.
