Question

Suppose that a manufacturer is testing one of its machines to make sure that the machine is producing more than 97% good parts (Ho: p=0.97 and HA: p> 0.97) The test results in a P-value of 0.102. In reality, the machine is producing 99% good parts. What probably happens as a result of the testing? o A. The researcher fails to reject Ho, making a Type 1 error. OB. The researcher correctly fails to reject Ho O C. The researcher rejects Ho, making a Type I error. O D. The researcher fails to reject Ho, making a Type Il error. Click to select your answer.

Explanation / Answer

Since p - value is large, researcher will fail to reject Ho whereas the percentage of good parts was actually more than 97%. Hence,

The researcher fails to reject Ho and made Type II Error.

Option D is correct.
