Answer:
Step-by-step explanation:
Given
The above data
Required
- A stem and leaf display
- The median
- The quartiles
First, determine the range of the data
Next, group each dataset base on common whole numbers.
So, we have:
Next, we construct the stem and leaf plot.
The whole numbers will be the stem while the decimal parts will be the leaf.
So, we have:
From the above plot,
The median is calculated as:
i.e. the median is at the 42nd position.
From the above stem and leaf plot.
The 42nd position is at stem 90 and the leaf .4
So the median is:
The lower quartile (Q) is calculated as:
i.e. the lower quartile is at the 21st position.
From the above stem and leaf plot.
The 42nd position is at stem 88 and the leaf .6
So the lower quartile is:
The upper quartile (Q3) is calculated as:
i.e. the upper quartile is at the 63rd position.
From the above stem and leaf plot.
The 63rd position is at stem 92 and the leaf .2
So the upper quartile is:
The form of linear equation that describes line is:
First we must calculate the slope.
Now it looks a bit more like this:
All we need now is to put in y and x from one point doesn't matter which. I'll pick A.
The equation now looks like this:
Solve for n.
And finally write the equation.
Hope this helps.
