See Answer →Creatinine excretion isa parameter of kidney function. Generally speaking, lower values indicate better health. This depends on body weight. A researcher conducted a study on creatinine excretion in test group and control group to find the efficacy of a new drug. The subjects were randomly divided. He included 100 subjects in each group but for this exercise consider only 10 subjects in each group. The data obtained on creatinine level in these 10 subjects are as follows:
| Test Group | 16.6 | 19.8 | 17.1 | 17.0 | 15.6 | 20.3 | 24.7 | 18.5 | 17.6 | 22.0 |
|---|---|---|---|---|---|---|---|---|---|---|
| Control Group | 23.2 | 22.0 | 21.9 | 16.7 | 14.2 | 23.2 | 24.8 | 25.5 | 28.1 | 21.8 |
Do you think that creatinine excretion was really lower in the test group on average?

See Answer →In a parallel-line assay, total 18 guinea pigs, 4 guinea pigs each from 3 different breeds were selected and classified into 4 groups for each breed. Two groups were administered with two doses of the standard preparation and remaining two groups with two doses of the test preparation. The responses of these doses are recorded in the following table:
ular form:
| Dose (Standard) | Dose (Test) | |||||
|---|---|---|---|---|---|---|
| Breed | 10 (in µL) | 15 (in µL) | 20 (in µL) | 5 (in µL) | 10 (in µL) | 15 (in µL) |
| 1 | 25 | 42 | 55 | 20 | 43 | 64 |
| 2 | 23 | 47 | 52 | 23 | 42 | 66 |
| 3 | 22 | 38 | 58 | 24 | 44 | 67 |
(i) Determine the dose-response regression models for both preparations.
(ii) Test whether the dose-response curves of both preparations are linear and parallel to each other or not.
(iii) Interpret whether the relative potency and its confidence interval can be computed or not.
