The following 5 questions are based on this information. Census indicates that the proportion of adult women in the United States is 49% (p=0.49).
We plan to take a random sample of 300 U.S. adults.
1)The sampling distribution of p is
2)The standard error (SE) of p is
3)What is the probability that a random sample of 300 U.S.adults will provide a sample proportion (p) that is within 0.04 of the population proportion (p)?
4)What is the probability that a random sample of 300 U.S. adults will provide a sample proportion (p) that is within 0.07 of the population proportion (p)?
5)Say, you took a random sample of 300 U.S. adults, and found out that the sample proportion (p) for this sample to be 0.38 (or 38%). In light of the result from thePRECEDING question,
please show step by step, equations . dumbproof it to the best of your ability
please dont type like this P[ |X(bar)-| <25] =P[ |(X(bar)-)/(/sqrt(n))| <25>
