2-3y is the answer u used distributive property to expand it
40 million foreign-born representing 13% of the population resided in the United States. The chart below shows the trends by decade, 1860-2010. It is adapted from the more detailed table that follows, which appears in Audrey Singer’s article,
Answer:
no
Step-by-step explanation:
Answer:
For the sampling distribution of the sample proportion for a sample of size 50, the mean is 0.061 and the standard deviation is 0.034.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean
and standard deviation 
In this question:

So
Mean:

Standard deviation:

For the sampling distribution of the sample proportion for a sample of size 50, the mean is 0.061 and the standard deviation is 0.034.
40 x 50 = 2000, 4 x 5 = 20, 2000/20 = 100
