Answer:
Step-by-step explanation:
Given that the number of orders received daily by an online vendor of used CDs (say X) is normally distributed with mean 270 and standard deviation 16.
X is N(270, 16)
To find percentage of days will the company have to hire extra help or pay overtime, we can find probability using std normal table
X>302 means
P(Z>2) = 0.25
Thus 25% of days will the company have to hire extra help or pay overtime
The slope is 3/2
Steps:
4 - (-2) = 6
5 - (-4) = 9
Put into a fraction, with the y sum on top.

To plot the graph of the data given, we have a lot of options, one common option to plot this kind of data is a column bar graph.
The picture attached show the column bar for the data given, assuming that the age was measured in years and the height was measured in feet.
Some resources that could help to plot data are excel, origin or qtiplot.
