Answer: 6.6

Step-by-Step Solution:

Values in the Data Set :-
6.1, 5.9, 4.2, 5.9, and 10.7

Sum of all Values (S) = 32.8
Number of Values (N) = 5

Mean of Data = S/N

Therefore,
= 32.8/5
= 328/50
= 6.56
=> 6.6

Mean of Data = 6.6

Answer:

6.6

Explanation:

the "mean" of a data set is what we commonly refer to as the average. We find this estimate of values by adding up all of the values of the data set, and then dividing by the number of values we added together.

{for example: the mean [average] of 1, 5, 6:

1 + 5 + 6 = 12

12 ÷ 3 [we have 3 numbers] = 4}

our values:

6.1 ; 5.9 ; 4.2 ; 5.9 ; 10.7

> 6.1 + 5.9 + 4.2 + 5.9 + 10.7 = 32.8

[we have 5 numbers]

32.8 / 5 = 6.56

when rounding a number, we look to the digit one place to the right. If it is greater than or equal to 5, we "round up" our digit [we move it up to the next digit]

if it is less than 5, we keep our digit the same

(the tenths place = _ . _ _ _ ones. tenths)

so if we round 6.56 to the nearest tenth:

6.56

[6 > 5]

6.6

So, the mean of this data set rounded to the nearest tenth is 6.6

hope this helps!!
