Question

question 8, 7.3.7 part 1 of 3 points: 0 of 1 unit 4 - mean, median and mode, and find the mean, median, and mode for the set of numbers. if necessary, round the mean to one decimal place. 219, 286, 567, 586, 325, 257, 531, 102 find the mean. select the correct choice below and, if necessary, fill in the answer box to complete your choice. a. the mean is (type a whole number or decimal rounded to one decimal place as needed. use a comma to separate answers as needed.) b. there is no mean.

Explanation:

Step1: Calculate sum of numbers

$219 + 286+567+586+325+257+531+102=2873$

Step2: Determine number of values

There are 8 numbers.

Step3: Calculate the mean

$\text{Mean}=\frac{2873}{8}=359.125\approx359.1$

Step4: Arrange numbers in ascending order

$102, 219, 257, 286, 325, 531, 567, 586$

Step5: Calculate the median

Since there are 8 (an even - numbered) values, the median is the average of the 4th and 5th values. $\text{Median}=\frac{286 + 325}{2}=\frac{611}{2}=305.5$

Step6: Determine the mode

No number repeats in the set, so there is no mode.

Answer:

Mean: 359.1
Median: 305.5
Mode: None
