Question

Solve the following problems. Round to the nearest tenth if necessary. Tomatoes Plants The heights ( in inches) of eight tomato plants are: 36, 45, 52, 40, 38, 41, 50, and 48

Answer 1

Heigths : 36, 45 , 52 , 40, 38, 41, 50, 48

a. range

Range is the difference between the highest and lowest values

Highest value = 52

Lowest value = 36

Range = 52-36 = 16

b. Mean = add all the values, and divide by the number of values:

36+45+52+40+38+41+50+48 = 350

There are 8 values

Mean = 350/8 = 43.75

Median: is the middle number among the values.

First, order the values from lowest to highest:

36 - 38 - 40 - 41 - 45 - 48- 50 -52

Since there are 2 numbers, add them and divide by 2

(41+45)/2 = 86/2 = 43

Mode

is the value that repeats the most.

Since there is no number that repeats itself, there is no mode
