Please refer to question 9-90. A manufacturer of interocular lenses is qualifying a new grinding machine and will qualify the machine if there is evidence that the percentage of polished lenses that contain surface defects does not exceed 2%. A random sample of 250 lenses contains six defective lenses. Formulate and test an appropriate set of hypotheses to determine if the machine can be qualified. Use α = 0.05. What is your alternative hypothesis?

p is equal to 0.02

p is greater than 0.02

p is less than 0.02

p is not equal to 0.02

What is the p (the true population parameter) and your conclusion from the previous question?

Reject the null, p is less than 0.02 at alpha = 0.05

Reject the null, p is not less than 0.02 at alpha = 0.05

Fail to reject the null, p is not less than 0.02 at alpha = 0.05

Fail to reject the null, p is less than 0.02 at alpha = 0.05

A treadmill manufacturer has developed a new machine with softer tread and better fans than its current model. The manufacturer believes these new features will enable runners to run for longer times than they can on its current machines. To determine whether the desired result is achieved, the manufacturer randomly sampled 35 runners. Each runner was measured for one week on the current machine and for one week on the new machine. The weekly total number of minutes for each...
