The mean of the sampling distribution is 0.35.
The standard error of the sampling distribution is 0.037
What is the mean of this distribution?
The mean of a sampling distribution is equal to the population proportion.
In this case, the population proportion is the efficacy of the drug, which is 0.35.
So, the mean of the sampling distribution is also 0.35.
What is the standard error of this distribution?
The standard error of a sampling distribution is calculated using
SE = √[p(1 - p)/n]
Substitute the known values into the equation
SE = √[0.35 * (1 - 0.35)/169]
Evaluate
SE = 0.037
Hence, the standard error of the sampling distribution is 0.037
