The table below represents three different tested areas. These areas were tested for blood infection. The result is for the number of white blood cells per cubic millimeter multiplied by 100. Determine which area had an infection higher than the other using the t-test method?

Use the standard normal table to find the z-score that corresponds to the cumulative area 0.0158. If the area is not in the table, use the entry closest to the area. If the area is halfway between two entries, use the z-score halfway between the corresponding z-scores. Click to view page 1 of the standard normal table. Click to view page 2 of the standard normal table. (Type an integer or decimal rounded to three decimal places as needed.)
