In a certain distribution of numbers, the mean is 50 with a standard deviation of 6. Use Chebyshev's theorem to tell the probability that a number lies in the indicated interval. Between 35 and 65 O A. At least 15 16 OB 1 At least 25 OC 4 At least 25 OD 21 At least 25
Example 13: Use Chebyshev's theorem with X = 68, n = 85 and S = 10 and do questions a- (a) Calculate the percentage (p) of data points that is within k =3 standard deviations of the mean. Substitute the given value of k into Chebyshev's formula and evaluate p • Write p as a percentage to one decimal place. p88.9% (b) Find the number of standard deviation (k) on either side of the mean that cuts off p=75% of...
