Question
The test statistic was found to be
?2 = 9.545.
For a test of independence between two categorical variables, there will be
(r − 1)(c − 1)
degrees of freedom where r is the number of rows and c is the number of columns from the observed frequencies. The given observed data are below.| Preferred Pace of Life | Gender | |
|---|---|---|
| Male | Female | |
| Slower | 229 | 217 |
| No Preference | 21 | 25 |
| Faster | 90 | 48 |
| Total | 340 | 290 |
There are
r =
rows for the preferred pace of life and
c =
columns for gender. Thus, there are
(r − 1 )(c − 1) =
degrees of freedom.Recalling that this is an upper tail test, use technology to find the p-value for
?2 = 9.545,
rounding the result to four decimal places.p−value =
