Answer:
Mean is 0.6.
Standard deviation is 0.059
Step-by-step explanation:
The first step is finding the sample proportion p.
Suppose Maria, a researcher, takes a random sample of 70 Americans and finds that 42 are over the age of 20.
This means that
What are the mean and standard deviation of the sampling distribution of p?
Mean:
The mean of a proportion is the same as the proportion. So the mean is 0.6
Standard deviation:
Proportion p in a sample of size n. The standard deviation is:
Sample size 70, so:
