Find the (a) mean, (b) median, (c) mode, and (d) midrange for the given sample data.

An experiment was conducted to determine whether a deficiency of carbon dioxide in the soil affects the phenotype of peas. Listed below are the phenotype codes where

1=smooth-yellow,

2=smooth-green,

3=wrinkled-yellow,

and

4=wrinkled-green.

Do the results make sense?

Part 1

(a) The mean phenotype code is

2.62.6.

(Round to the nearest tenth as needed.)

Part 2

(b) The median phenotype code is

33.

(Type an integer or a decimal.)

Part 3

(c) Select the correct choice below and fill in any answer boxes within your choice.

A.

The mode phenotype code is

33.

(Use a comma to separate answers as needed.)

B.

There is no mode.

Part 4

(d) The midrange of the phenotype codes is

2.52.5.

(Type an integer or a decimal.)

Part 5

Do the measures of center make sense?

A.

Only the mode makes sense since the data is nominal.

B.

All the measures of center make sense since the data is numerical.

C.

Only the mean, median, and midrange make sense since the data is nominal.

D.

Only the mean, median, and mode make sense since the data is numerical
