Answer:
Mean 1.580666667 1.769333333
Standard Deviation 0.890741799 1.123161779
Step-by-step explanation:
When we run the commands in the R software we get the graphs as follows.
The commands were
qqnorm(c(0.32,0.52,0.77,0.81,0.96,1.2,1.31,1.43,1.62,1.87,1.95,2.1,2.48,3,3.37))
and
qqnorm(c(0.47,0.59,0.81,0.9,1.18,1.2,1.35,1.51,1.74,1.89,2.05,2.2,2.81,3.09,4.75))
We can plot the graphs in any other plotting software .
The results would be same .
We see there's a slight difference between the two graphs.
One curve goes above ( Minneapolis) for 0.4 and the other ( for St Paul) is below 0.4
