This problem asks you to test whether the far western United States families distribution fits the distribution of the American families. The dfs are the number of cells – 1 = 5 – 1 = 4 (Use a computer or calculator to find the p-value. To find the p-value, calculate P( χ 2 > 3). Make a chart with the following headings and fill in the columns:
This time, calculate the χ 2 test statistic by hand. The values in the table are the observed ( O) values or data. These numbers are the expected ( E) values. If the absent days occur with equal frequencies, then, out of 60 absent days (the total in the sample: 15 + 12 + 9 + 9 + 15 = 60), there would be 12 absences on Monday, 12 on Tuesday, 12 on Wednesday, 12 on Thursday, and 12 on Friday. H a: The absent days occur with unequal frequencies, that is, they do not fit a uniform distribution.
