There are 10 spaces in between holes so the center to center distance between the first and last hole is \left(10\right)\left(4\:\frac{1}{4}\right)=\left(10\right)\left(\frac{17}{4}\right)=\frac{170}{4}=42\:\frac{1}{2}\:\:\imaginaryI nches

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]
