a. The central limit theorem says that the histogram of sample means (from many large samples) will look more and more Normal.
e. The histogram of the sample data values will look like the population distribution, whatever it might happen to be.
The sampling distributions of means of large sample size is always normal when approximated. It doesn't matter whether the population is normal or it is not, as long as the population is above 30 (30 is considered large enough), then the sampling distribution of means will be approximately normal.
Also, as a general behaviour of the histogram, the central limit theorem states that irrespective of the shape the population distribution takes, the sampling distribution of the sample means approaches a normal distribution as the sample size will get bigger.

Answer:
Before her donation, Marie owned 35 comic books.
Step-by-step explanation:
Marie donated 40% of her comic books to a school, that is, Marie donated 40 comic books per 100 comic books she owned. We can write it as a ratio: the ratio of donated comic books to total comic books is 100:40. If she donated 14 comic books, the number of comic books she owned before her donation were:
14 donated cb × (100 total cb/40 donated cb) = 35 total cb
