Coffee beans: Shipments of coffee beans are checked for moisture content. A high moisture content indicates water contamination and will result in the shipment being rejected. Let μ represent the mean water content (in percent by weight) in a shipment. Fifty moisture measurements will be made on beans chosen at random from the shipment. A test of the hypotheses H0: μ = 10 versus H1: μ > 10 will be made at the α = 0.05 level of significance. Assume the standard deviation of moisture content is σ = 5.0.

Find the power of the test against the alternative μ1 = 12.

    A machine in the student lounge dispenses coffee. The average cup of coffee is supposed to contain 7.0 ounces. A random sample of eight cups of coffee from this machine show the average content to be 7.4 ounces with a standard deviation of 0.70 ounce. Do you think that the machine has slipped out of adjustment and that the average amount of coffee per cup is different from 7 ounces? Use a 5% level of significance. What are we testing...

    The nicotine content in cigarettes of a certain brand is Normally distributed with a standard deviation of σ = 0.1 milligrams. The brand advertises that the mean nicotine content of their cigarettes is μ = 1.5, but you are suspicious and plan to investigate the advertised claim by testing the hypotheses H0 : μ = 1.5 versus Ha : μ > 1.5 at the 5% significance level. You will do so by measuring the nicotine content of 15 randomly selected...

    The fan blades on commercial jet engines must be replaced when wear on these parts indicates too much variability to pass inspection. If a single fan blade broke during operation, it could severely endanger a flight. A large engine contains thousands of fan blades, and safety regulations require that variability measurements on the population of all blades not exceed σ2 = 0.18 mm2. An engine inspector took a random sample of 81 fan blades from an engine. She measured each...

    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...
