Question

The 50-year average of the mean annual temperatures at eight sites in Phoenix are shown below. Check the assumption of normality in the population with a probability plot. Construct a 95

Answer 1

To check the assumption of normality, construct a probability plot comparing the observed data to the expected values from a normal distribution.

Step-by-step explanation:

To check the assumption of normality in the population, we can construct a probability plot. This plot compares the observed data to the expected values from a normal distribution. If the points on the plot are roughly in a straight line, it suggests the data follows a normal distribution.

To construct a 95th percentile probability plot, you would plot the mean annual temperatures at the eight sites in Phoenix against the expected values from a normal distribution. If the points on the plot fall roughly in a straight line, we can assume normality in the population. If the points deviate significantly from a straight line, it suggests non-normality.
