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. Describe the shape of the data distribution. Do you see any outliers? b. Use the stem and leaf plot to find the smallest observation. c. Find the eighth and ninth largest observation

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

StemLeaf

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

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

i got 10.28 but that rounds up to 10.3
