Answer 17

sorr y thats not right its 36.2

Answer 18

I'm getting 37.13 as the mean.

Answer 19

Regardless, the next step is to find the median value. There are 15 values, we need the 7th one. (35)

Answer 20

Now, we need to find the medians of the two data sets above and below the median. Since 35 is a datum, we exclude it. These two medians represent the first and third quartiles of the data and define the bounds of our box.

The data set below 35 is 25, 27, 28, 30,30,33,34. The median of this is 30.
The data set above 35 is 40, 40, 41, 45, 49, 50,50. The median of this is 45.

Answer 21

We now have our box. It should be between 30 and 45 on the number line. Within our box, we mark the second quartile, which is the median of the entire data set (35). The whiskers extend from the box to the highest and lowest values in the data set (maximum and minimum). These are 25 and 50.

Answer 22

I'm sorry. We don't actually need to know the mean.
