The mean score on a driving exam for a group of driver's education students is 80 points, with a standard deviation of 5 points. Apply Chebychev's Theorem to the data using
kequals=2. Interpret the results.
At least __ % of the exam scores fall between __ and __
(Simplify your answers.)
Given the mean score on a driving exam for a group of drivers education students is 80 points, with the standard deviation of 5 points.
According to Chebycheev's theorem off the data points falls between k standard deviation of the mean.
Here k=2
Thus
Hence at least 75% of the observations falls between two standard deviation of mean. That is
80-2*5 and 80+2*5
That is
70 and 90.
