Toplam ürün sayısı=1000 Her kümedeki ürün sayısı=20 Küme sayısı= Toplam ürün sayısı/Her kümedeki ürün sayısı Küme sayısı = 5 Yani 50 küme seçilmelidir. Bir ürünün seçilme olasılığını bulmak için, seçilen ürünlerin üretilen toplam ürün sayısına göre oranını dikkate almamız gerekir: Bir ürünün seçilme olasılığı Her kümedeki ürün sayısı/Toplam ürün sayısı. Bir ürünün seçilme olasılığı 20/1000 = 0,02. Yani bir ürünün seçilme olasılığı 0,02 yani %2'dir.

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]
