At least once a week | 220.25 | 151.75 |
At least once a day | 612.19 | 421.81 |
Explanation of Solution
Given:
The table is:
Use Facebook | Main Campus | Common wealth |
Several times a month or less | 55 | 76 |
At least once a week | 215 | 157 |
At least once a day | 640 | 394 |
Total Facebook users | 910 | 627 |
Formula used:
The formula to compute the degree of freedom is:
Calculation:
The expected counts could be computed as:
Use Facebook | Main Campus | Common wealth |
Several times a month or less | ||
At least once a week | ||
At least once a day |
Thus, the expected counts are:
Use Facebook | Main Campus | Common wealth |
Several times a month or less | 77.56 | 53.44 |
At least once a week | 220.25 | 151.75 |
At least once a day | 612.19 | 421.81 |
