Construct a stem and leaf plot for these 50 measurements: 3.1 4.9 2.8 3.6 2.5 4.5 3.5 3.7 4.1 4.9 2.9 2.1 3.5 4.0 3.7 2.7 4.0 4.4 3.7 4.2 3.8 6.2 2.5 2.9 2.8 5.1 1.8 5.6 2.2 3.4 2.5 3.6 5.1 4.8 1.6 3.6 6.1 4.7 3.9 3.9 4.3 5.7 3.7 4.6 4.0 5.6 4.9 4.2 3.1 3.9 a.

Jensen Baxter · Answer 1

a) Bell shape, similar to normal

b) Smallest observation: 1.6

c) 8th largest observation: 4.9

9th largest observation: 4.9

Step-by-step explanation:

The stem and leaf plot for this series is

Stem Leaf

1 6 8

2 1 2 5 5 5 7 8 8 9 9

3 1 1 4 5 5 6 6 6 7 7 7 7 8 9 9 9

4 0 0 0 1 2 2 3 4 5 6 7 8 9 9 9

5 1 1 6 6 7

6 1 2

The shape suggested by this plot is a bell-shape, similar to a normal distribution.

The smallest value is the first one that appears in the plot: 1.6.

The eighth and ninth larges observation has to be counted backwards from the largest (6.2).

8th largest observation: 4.9

9th largest observation: 4.9
