Question

Suppose that the efficacy of a certain drug is 0.36. Consider the sampling distribution (sample size n = 186) for the proportion of patients cured by this drug. What is the mean of this distribution?

Option 1) 0.36
Option 2) 0.64
Option 3) 0.500
Option 4) 0.250

Answer 1

The mean of the sampling distribution for the efficacy of the drug, with a known cure rate of 0.36, is also 0.36.

Step-by-step explanation:

The question pertains to the sampling distribution of the proportion of patients cured by a drug with known efficacy. When the efficacy rate of a drug is 0.36, this figure represents the probability that a randomly selected patient will be cured by the drug. In the context of a sampling distribution for a sample size of 186 patients, the mean of this distribution would be the same as the population proportion, which means that the mean of the sampling distribution for the cure rate is 0.36.
