Step-by-step explanation:
I don't really know what to do either.

Answer:
a.is approximately normal because of the central limit theorem.
Step-by-step explanation:
The central limit theorem states that if we have a population with mean μ and standard deviation σ and we take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately normally distributed.
For any distribution if the number of samples n ≥ 30, the sample distribution will be approximately normal.
Since in our question, the sample of observations is 50, n = 50.
Since 50 > 30, then <u>our sample distribution will be approximately normal because of the central limit theorem.</u>
So, a is the answer.
Its C. The point is at 3 and goes down, therefore C.
9^2/9^7
when dividing powers, we subtract the exponents
9^(2-7)
9^ (-5)
a negative exponent flips from the numerator to the denominator
1/ 9^5
Choice D
