  • Question of Hypothesis !! Help !!?

    Does the use of fancy fonts slow down the reading of text on computer screens? Adults can read 4 paragraphs of text in an average time of 22 seconds in the common Times New Roman font. The standard deviation is known to be 4 seconds. A random sample of 25 adults was asked to read four of the same type of paragraphs in the ornate font named Gigi (Gigi). Their times (in seconds) were recorded and are listed below:

    19.7 23.6 21.8 30.1 24.2 31.2 22.7 22.9 24.6 18.8 28.7 20.6 18.8

    27.6 24.7 23.6 29.7 28.8 22.7 29.4 23.8 29.3 25.5 24.9 19.2

    Can you conclude that the mean reading time for Gigi is greater than 22 seconds? Use a 5% test. What is the p–value for this test?
