Question
![Suppose that the efficacy of a certain drug is 0.43. Consider the sampling distribution (sample size \( n = 180 \)) for the proportion of patients cured by this drug.
**What is the mean of this distribution?**
- The mean is \( 0.43 \) ✔️
**What is the standard error of this distribution? Round your answer to two decimal places.**
- Incorrect answer provided: \( 0.57 \) ❌
**Instructions:** Enter an integer or decimal number. [more...]
**Explanation:**
The mean of the sampling distribution is equal to the population proportion \( p \), which is \( 0.43 \). The standard error (SE) of this distribution can be calculated using the formula for the standard error of a proportion:
\[
SE = \sqrt{\frac{p(1-p)}{n}}
\]
where \( p \) is the population proportion, and \( n \) is the sample size.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F88c4a12b-1ea9-44c1-9400-53c8c9c9bde6%2Fcafa47af-2923-46c3-9acb-f9290825a193%2Ff92aci9_processed.png&w=3840&q=75)
