To obtain information on the corrosion-resistance properties of a certain type of steel conduit, 35 specimens were buried in soil for an extended period. the maximum penetration (in mils) was then measured for each specimen, yielding a sample mean penetration of 52.7 mils and a sample standard deviation of 4.8 mils. the conduits were manufactured with the specification that true mean penetration be at most 50 mils. does the sample data indicate that specifications have not been met? state the relevant hypotheses, calculate the value of the appropriate z statistic, determine the p-value (including a picture of it) and state your conclusion at the 0.05 significance level.
