Construct a normal probability plot for these data. Do they appear to come from an approximately normal distribution?

Step-by-Step Solution:

Step 1 of 1:

Given the below are the duration (in minute) of 40 time intervals between eruptions of the geyser old faithful in yellowstone national park.

Here n=40.

Our goal is:

We need to construct a normal probability plot for these data and

We need to find do these data appear to come from an approximately normal population.

The formula of the cumulative probability is

=

Where i = 1,2,3,...,40.

And n=40.

Now we have to construct a normal probability plot for these data.

We are using excel to plot the normal probability.

First we sorted  values.

We are using =NORMSINV function to find the .

=NORMSINV(0.0125)

Then we get value is -2.241402728.

The data is given below.

 i i ...
