5. Applying Chebyshev’s Theorem: (Be as detailed as possible thanks)
a. According to the Chebyshev’s theorem, at least what percentage of the data fall within 2 standard deviations either side of the mean?
b. What’s the actual percentage of the data fall within 2 standard deviations either side of the mean?
c. According to the Chebyshev’s theorem, at least what percentage of the data fall within 3 standard deviations either side of the mean?
d. What’s the actual percentage of the data fall within 3 standard deviations either side of the mean?
Ans from my teacher. 75%, 34/37=92%, 8/9, 100%
a)from Chebychev ; % of values k standard deviation from mean =(1-1/k2)*100
hence percentage of the data fall within 2 standard deviations either side of the mean
=(1-1/22)*100=(3/4)*100 =75.0%
b)for this the data is required which is not available here ;it seems 34 of 37 data values are within 2 standard deviation from the answer
c)
percentage of the data fall within 3 standard deviations either side of the mean =(1-1/32)*100
=(8/9)*100=88.89%
d)
data is required which is not available here ;it seems 37 of 37 data values are within 3 standard deviation
