Problem 3. An article in Human Factors (June 1989) presented data on visual accommodation (a function of eyemovement) 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 visualaccommodation is normally distributed?

Beef Consumption. According to Food Consumption, Prices, and Expenditures, published by the U.S. Department of Agriculture, the mean consumption of beef per person in 2011 was 57.5 lb. A sample of 40 people taken this year yielded the data, in pounds, on last year’s beef consumption given on the WeissStats site. Use the technology of your choice to do the following. a. Obtain a normal probability plot, a boxplot, a histogram, and a stem-and-leaf diagram of the data on beef consumptions. b. Decide, at the 5% significance level, whether last year’s mean beef consumption is less than the 2011 mean of 57.5 lb. Apply the onemean t-test. c.
