                 Does the use of fancy type fonts slow down   the reading of text on a computer screen?  Adults can read 4   paragraphs of text in an average time of 22 seconds in the common Times New   Roman font.  Ask 25 adults to read this text in the ornate font   named Gigi.  Here are their times:                                  23.2 34.2 31.5 21.2 23.9 24.6 28.9 26.8 23 27.7 20.5 28.6 29.1 34.3 24.4 27.3 21.4 28.1 16.1 32.6 41.3 22.6 26.2 25.6  34.1                               Suppose   that reading times are Normal with standard deviation = 6   seconds.  Is there good evidence that the mean reading time for   Gigi is greater than 22 seconds?  Follow the 4 step process.
