A primary measure of dispersion for sample data is the sample standard deviation, s.  Choose the best option to explain what the meaning of the sample standard deviation is, in general.   A. The distance between one observation and the mean. B. The average distance of an observation from the middle of the distribution. C. The average distance between observations in the sample. D. The distance between the third and first quartiles.

JU UI LIle uala Values will fall within 3 standard deviations of the mean. 15. A report stated that the average number of times a cat returns to its food bowl during the day is 15.2. Suppose that the data is approximately bell-shaped with a standard deviation of 4.16. a. What percentage of cats would return to their food bowl between 2.72 and 27.68 times per day? b. Now, assume the data is NOT bell-shaped. What percentage of cats would return to their food bowl between 2.72 and 27.68 times per day? Use Chebyshev's Theorem.
