Given the information provided, we know that classic literature books in Elizabeth's store are "a bit worn out but rare and valuable." Non-fiction books are common, and some are in excellent condition.

From the scenario where Elizabeth comes across a book that feels brand new, it is necessarily true that she found a non-fiction book that is in excellent condition.

Therefore, the conclusion that is necessarily true is: Elizabeth found a non-fiction book that is common. The other conclusions cannot be determined from the given information.

\boxed{\text{Elizabeth found a non-fiction book that is common}.}

We plan to test whether the mean mRNA expression level differs between two strains of yeast, for each of 8,000 genes. We will measure the expression levels of each gene, in n samples of strain 1 and m samples of strain 2. We plan to compute a P-value for each gene, using an unpaired two-sample t-test for each gene (the particular type of test does not matter). a) What are the null hypotheses in these tests (in words)? [2] b) If, in fact, the two strains are identical, how many of these tests do we expect to produce a P-value exceeding 1/4? [2]
