Which of the following are correct general statements about the Central Limit Theorem? Select all that apply.
1. It specifies the specific shape of the curve which approximates certain sampling distributions.
2. It’s name is often abbreviated by the three capital letters CLT
3. The word Central within its name, is meant to signify its role of central importance in the mathematics of probability and statistics.
4. The accuracy of the approximation it provides, improves when the trial success proportion p is closer to $50 %$ .
5. It specifies the specific mean of the curve which approximates certain sampling distributions.
6. The accuracy of the approximation it provides, improves as the sample size n increases.
7. It specifies the specific standard deviation of the curve which approximates certain sampling distributions.
8. It is a special example of the particular type of theorems in mathematics, which are called limit theorems.

There were 855 major league baseball players in 2012 and their mean salary was $m = 3.44$ million dollars with standard deviation $s = 4.70$ million dollars.If we take random samples of size $n = 30$ players and calculate the mean salary, in millions of dollars, of each sample, describe the shape, center, and standard error of the distribution of sample means.

After hearing of the national result that 44% of students engage in binge drinking (5 dri
a sitting for men, 4 for women), a professor surveyed a random sample of 244 students at his college and found that 96 of them admitted to binge drinking in the past week. Should he be surprised at this result? Explain.

Check whether the standard error of the sampling distributions of bar p obtained in part(a) and part(b) are different.

In simple terms, this mathematical branch will be familiar to students dealing with probability distribution and statistics as you seek answers to your random sample statistic equations. Take a look at the sampling distribution example that will make things clearer regardless of your subject. If you need additional help, consider sampling distribution examples with solutions that will have all the questions that will look alike to what you may have with your statistics regardless if there are sampling distribution problems or a complex sampling distribution equation. As always, start with sampling distribution questions first to identify the most efficient solution.
