For a chi-square test of homogeneity for this contingency table, what are the observed frequencies for the first row?
A clinic administers two drugs to two groups of randomly assigned patients to cure the same disease: 70 patients received Drug I and 8ea patients received Drug II. The following table gives the information about the numbers of patients cured and those not cured by each of these two drugs.
| Drug | Cured | Not Cured |
|---|---|---|
| I | 60 | 10 |
| II | 59 | 21 |
For a chi-square test of homogeneity for this contingency table, what are the observed frequencies for the first row?
Homework Answers
We need to state the observed frequencies of the first row which is directly given in the contingency table.
So,
Observed frequency for first row will be:
Observed frequency for cured from Drug I (Row 1, Column 1) = 60
Observed frequency for not cured from Drug I (Row 1, Column 2) = 10
