In this problem, we explore the effect on the standard deviation
of multiplying each data value in a data set by the same constant.
Consider the data set 17, 5, 10, 9, 4.
(a) Use the defining formula, the computation formula, or a
calculator to compute s. (Round your answer to one decimal place.)
s =
(b) Multiply each data value by 3 to obtain the new data set 51,
15, 30, 27, 12. Compute s. (Round your answer to...

3. Find the standard deviation of the data set 1,2,3,4,5) using the formula from class/discussion section. Do not use a computer/program to skip all the work. Then, find the IQR. When breaking the data into two pieces, do not include the median in either piece. 4. Find the standard deviation of the data set f-2n, -2n+2,..,-2,0,2,..,2n-2,2n). Simplify your answer as much as possible. Recall that in calculus you learned simpleformulas for i Σ2 and Σί3....
