Chapter 2:
11. The mean is 2, the median is 2, the sum of squared deviations is -52, the variance is -2.47, and the standard deviation is 1.57.
12. The mean is 1.361, the median is 1.3124, the sum of squared deviations is 0.07608920.0190223, the variance is 0.0190223, and the standard deviation is 0.1379213544.
13. The mean is 3.16667, the median is 3.25, the sum of squared deviations is 0.5333333334, the variance is 0.10667, and the squared deviation is 0.32660.
16. The Governors’ mean is 43 and the standard deviation is 6.83. The CEOs’ mean is 44 and the standard deviation is 12.65. By finding the mean of the Governor’s desk is to get the average and the standard deviation is the spread of the group’s scores. The means are very close together and are pretty much the same but the deviations are not and the deviations show that the CEOs’ desk were larger than the Governors’.*…show more content…*

The table shows that there is no huge difference in numbers. Whether the face was black or white, the results were very similar and in close range. The standard deviation was also around the same range for both experiments. It seems as if there were no signs of racism in this

1179 Words | 5 PagesI first start with 0.00 less than the probability which is 0.20 then we start at 0.21 less than 0.53. I came up with 0.53 from adding the initial probability of 0.20 and the second 0.33. Next I start at 0.54 less than 0.90 these figures come from adding 0.53 plus the third probability of 0.37. Lastly, I start at 0.91 less than 1 and again I adding 0.90 plus the last probability of 0.10. Now let’s find the Average materials cost per unit.
