Question

the depths (in inches) at which 10 artifacts are found are listed. complete parts (a) and (b) below.

25.5 39.3 24.5 23.2 44.4 28.8 29.9 35.1 34.5 22.4

(a) find the range of the data set.

range = 22
(round to the nearest tenth as needed.)

(b) change 44.4 to 55.7 and find the range of the new data set.

range =
(round to the nearest tenth as needed.)

Explanation:

Identify the given data set

Using the Range Calculation knowledge point
The given data set representing the depths (in inches) of 10 artifacts is:

$$ \{25.5, 39.3, 24.5, 23.2, 44.4, 28.8, 29.9, 35.1, 34.5, 22.4\} $$

Find the range of the original data set

Using the Range Calculation knowledge point

$$
LATEXBLOCK0
$$

Find the range of the modified data set

Using the Range Calculation knowledge point

$$
LATEXBLOCK1
$$

Answer:

Question 1

Range = 22.0

Question 2

Range = 33.3
