Let us compare the failure times of a certain type of light bulb produced by two different manufacturers, X and Y, by testing 10 bulbs selected at random from each of the outputs. The data, in hundreds of hours used before failure, are
(a) Use the Wilcoxon test to test the equality of medians of the failure times at the approximate 5% significance level. What is the p-value?
(b) Construct and interpret a q–q plot of these data. Hint: This is a q–q plot of the empirical distribution of X against that of Y.
14.1 Translation is the biological polymerization of amino acids into polypeptide chains This process requires – amino acids – messenger RNA (mRNA) – transfer RNA (tRNA) Ribosomes consist of ribosomal proteins and ribosomal RNAs (rRNAs) They have a large subunit and a small subunit (Figure 14.1) The rRNAs perform important catalytic functions associated...
