Answer
a) 0 mg and 1000 mg.
b) 3000, 4000, 11000, 12000, and 14000.
Work Step by Step
The plot specifies a leaf unit by which to multiply each observation. In this case: Leaf Unit 1000
a) 00 x 1000 = 0 mg
01 x 1000 = 1000 mg
b) When we look at the Steam and Leaf Plot, we notice that the most frequents outcomes are : 03, 04, 11, 12, and 14, so:
03 x 1000= 3000 mg
04 x 1000= 4000 mg
11 x 1000= 11000 mg
12 x 1000= 12000 mg
14 x 1000 = 14000 mg
