To obtain information on the corrosion-resistance properties of a certain type of steel conduit, 45
specimens are buried in soil for a 2-year period. The maximum penetration (in mils) for each specimen
is then measured, yielding a sample average penetration of x = 53.3 and a sample standard deviation of
s = 4.1. The conduits were manufactured with the specification that true average penetration be at mos
50 mils. They will be used unless it can be demonstrated conclusively that the specification has not been
met. What would you conclude? (Use a = 0.05.)
State the appropriate null and alternative hypotheses.
O Ho: H = 50
HgiH > 50

Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places
and your P-value to four decimal places.)

Is the following statement true or false and why: If we do not reject ?0H0, then we conclude that ?1H1 is false. Washers used in a certain application are supposed to have a thickness of 2 millimeters. A quality control engineering measures the thickness for a sample of washers and tests ?0:?=2H0:μ=2 versus ?1:?≠0H1:μ≠0. If a Type I error is made, what conclusion will be drawn regarding the mean washer thickness?

There is a 3 percent error rate at a specii c point in a production process. If an inspector isplaced at this point, all the errors can be detected and eliminated. However, the inspectoris paid $8 per hour and can inspect units in the process at the rate of 30 per hour.If no inspector is used and defects are allowed to pass this point, there is a cost of $10per unit to correct the defect later on.Should an inspector be hired?
