Problem #4: Note that this question (along with all other problems that don't have the Minitab symbol beside them) should be done by hand. Consider the following data, $$ 43,65, 48, 47,59,60,65,46,44,41 \text {. } $$ (a) Draw a stem and leaf plot including depths using intervals of length 5. (See the last page of this example for an explanation of depths). Enter the value of the depths only in the answer box below. For example, if your stem-and-leaf plot looked like the one on the last page of this example then you would enter the following numbers into the answer box: $8,36,20,44,21,5,1$ (b) Calculate the mean. (c) Calculate the sample variance. (d) Calculate the range. Problem $ eq 4(3): 3,3,4,3,2,1 \quad$ depths, separated with commas Problem $z 4(b): 51.80 \quad$ mean (rounded to 2 decimals) Problem $\& 4(\mathrm{C}): 88.18 \quad$ sample variance (rounded to 2 decimals) Froblem $\# 4(d): 24 \quad$ range Just Save Submit Problem as for Grading SP.VS. 828
