A set of n = 10 measurements consists of the values 5, 2, 3, 6, 1, 2, 4, 5, 1, 3.
a. Use the range approximation to estimate the value of s for this set. (HINT: Use the table at the end of Section 2.5.)
b. Use your calculator to find the actual value of s. Is the actual value close to your estimate in part a?
c. Draw a dotplot of this data set. Are the data moundshaped?
d. Can you use Tchebysheff’s Theorem to describe this data set? Why or why not?
e. Can you use the Empirical Rule to describe this data set? Why or why not?
