Question

The mean of the following numbers 2.3,
2.1, 0.75, 0.25, 2.8, 0.9,
and 15 is____
A. 1.6375
B. 1.7635
C. 1.5376
D. 1.6735

Answer 1

To find the mean of the given numbers, you need to add them up and divide by the total number of values.

2.3 + 2.1 + 0.75 + 0.25 + 2.8 + 0.9 + 15 = 24.1

There are 7 values, so divide 24.1 by 7:

24.1/7 = 3.4428571428571427

Rounded to four decimal places, the mean is approximately 3.4429.

None of the given options match this mean, so the correct answer is not provided.
