Answer :
Chebyshev's theorem states that for a large class of distributions, no more than 1/k² of the distribution will be k standard deviations away from the mean.
This means that 1 - 1/k² of the distribution will be within k standard deviations from the mean.
Because k = 1.8, the amount of the distribution that is within 1.8 standard deviations from the mean is
1 - 1/1.8² = 0.6914 = 69.14%
Answer: 69.1%
This means that 1 - 1/k² of the distribution will be within k standard deviations from the mean.
Because k = 1.8, the amount of the distribution that is within 1.8 standard deviations from the mean is
1 - 1/1.8² = 0.6914 = 69.14%
Answer: 69.1%
Answer:
84
Step-by-step explanation:
Chebyshev's Theorem states that the proportion of data values that lie within k=2.5 standard deviations of the mean is at least
1−1k2=1−12.52=0.84
So at least 84% of the data lies within 2.5 standard deviations of the mean, for any distribution.
