Answer:
Step-by-step explanation:
Given that you drew all possible random samples of size 1,000 from the population of LSAT test takers
Plotted the values of the mean from each sample
As per central limit theorem, we find that for sample sizes of minimum 30, the means of all such samples randomly drawn would follow a bell shaped curve with normal distribution irrespective of the original distribution of the population.
Hence here answer is yes, this would be a normal distribution as per central limit theorem.

Answer:
8
Step-by-step explanation:
ok so this is just the first one but i think you use a variable for what you are trying to find out, and well call this x and then u subtract the variable from the product of the rate and the amount, and once you have it, you multiply it but its own conjugate so then u use the binomial that you get to create a function, and you can graph it if you want, and u can use the apothem (the formula involves cos, so you might need a calculator) of the polygon created on your graph to find the domain, which you will then get the 4th root of, which is your answer. anyway, i believe this is what it is, but i may be wrong. hope this helps!
