Provide an appropriate response.Use Chebychev's rule to make a statement about the percentage of observations that lie within two standard deviations of the mean, for any data set. If the distribution of the data is actually bell-shaped, do you think that this estimate will be very precise? Why or why not?
What will be an ideal response?
According to Chebychev's rule, at least 75% of the observations in any data set lie within two standard deviations of the mean. If the distribution of the data is actually bell-shaped, the percentage of observations lying within two standard deviations of the mean will actually be much higher (roughly 95%).
