Question
Conduct the appropriate hypothesis test and compute the test statistic.
A company that produces fishing line undergoes random testing to see if their fishing
line holds up to the advertised specifications. Currently they are producing 30-pound
test line and 20 randomly selected pieces are selected to test the strength. The 20
pieces broke with an average force of 29.1 pounds and a sample standard deviation
of 2 pounds. Assuming that the strength of the fishing line is normally distributed,
perform the appropriate hypothesis test at a 0.05 significance level in order to
determine whether there is sufficient sample evidence to conclude the fishing line
breaks with an average force of less than 30 pounds.
Cannot be determined
) Yes, because the test statistic is -2.01
O No, because the test statistic is -2.01
O Yes, because the test statistic is -2.52
O No, because the test statistic is -2.52
