A cognitive Psychologist is interested to see if the color of the font when reading affects the speed at which a person recognizes words. Based on published studies, it is known that on average the general population takes µ = 650 milliseconds to recognize common words like apple, but the standard deviation for the population varies across these studies, so we do not know the population deviation.
The psychologist presents a sample of n = 25 participants with common words that are names of colors. However, the color names are shown in a color of font different from the word itself. That is, the word red is printed in blue, or green is printed in brown etc.
