Problem 7E

Can the plot in Exercise 6 be used to determine whether the PM data appear to come from a lognormal population? Explain.

Step-by-Step Solution:

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.
