Question 700:



No answer provided yet.Part A
Based on the data, we can infer that the data is right skewed, meaning the tail points off to the right. We can tell this because the mean is greater than the median and mode.

Part B
Chebyshev's Theorem states that the proportion of data that lie within K standard deviations of the mean is at least
1- (1/K2)   and we're given two data points which are 2 standard deviations above and below the mean, so plugging in the values we get 1-(1/4) = .75 . So at least 75% of the processors lie within these values.

Part C
Since there is some evidence the data is right skewed, that means some very large values are pulling the mean up. This makes the mean a bit deceiving as a measure of central tendency, especially to buyers of PCs.
