Name HYPOTHESIS TESTING AND ESTIMATION EXERCISE:-TEST In controlling the quality of a new drug, a dose of medicine is to contain an average of 250 parts per million (ppm) of a certain chemical. When the average concentration is 250 ppm, the population standard deviation of the chemical concentration is known to be 9.7 ppm. If the average concentration is below 250 ppm, the drug may be ineffective. The manufacturer wants to check whether the average concentration of the chemical in...

The price to earnings ratio (P/E) is an important tool in financial work. A random sample of 14 large U.S. banks (J. P. Morgan, Bank of America, and others) gave the following P/E ratios.† 24 16 22 14 12 13 17 22 15 19 23 13 11 18 The sample mean is x ≈ 17.1. Generally speaking, a low P/E ratio indicates a "value" or bargain stock. Suppose a recent copy of a magazine indicated that the P/E ratio of...
