1. Find the mean and range of the following data. 14, 14, 15, 15, 16, 15, 15, 16
A 15; 2
B 15; 15
C 12; 15
D 12; 2

Option A) 15; 2

Step-by-step explanation:

The mean is the average of the numbers.

The mean is sum of terms/number of terms

[Here terms means the data]

= 14+14+15+15+15+15+16+16/8

= 120/8

= 15

The range of a set of data is the difference between the highest and lowest values in the set. To find the range, subtract the smallest value from the largest value in the set.

Smallest= 14

Greatest= 16

Therefore range=

16-14

= 2

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]
