Can the plot in Exercise 6 be used to determine whether the PM data appear to come from a lognormal population? Explain.
Step 1 of 1:
From exercise 6 we know that n is 62
Our goal is:
We need to determine whether the the PM data appears to come from a lognormal population and we need to explain.
Now we have to determine whether the the PM data appears to come from a lognormal population.
Here we sorted values.
The formula of the cumulative probability is
=
Where i = 1,2,3,...,n.
And n=62.
