Question
Problem 3. An article in Human Factors (June 1989) presented data on visual accommodation (a function of eye movement) when recognizing a speckle pattern on a high-resolution CRT screen. The data are as follows: 36.45, 67.90, 38.77, 42.18, 26.72, 50.77, 39.30, and 49.71. a. Calculate the sample mean and sample standard deviation. b. Construct a dot diagram of the data. c. Construct a normal probability plot of the visual accommodation data given. Does it seem reasonable to assume that visual accommodation is normally distributed?
