A quality-assurance inspector periodically examines the output of a machine to determine whether it is properly adjusted. When set properly, the machine produces nails having a mean length of 2.000 cms, with a standard deviation of 0.070 cms. For a sample of 35 nails, the mean length is 2.025 cms. The correct conclusion at a 10% significance level if the test statistic value is 2.113, is: O A. Fail to accept the null hypothesis. The machine produce nails with mean length of 2.000 cms. O B. Do not reject null hypothesis, the machine does not produce nails with mean length of 2.000 cms. O C. Do not reject null hypothesis, the machine produce nails with mean length of 2.000 cms. O D. Fail to accept the null hypothesis. The machine does not produce nails with mean length of 2.000 cms.

![A quality-assurance inspector periodically examines the output of a machine to determine whether it is properly adjusted.
When set properly, the machine produces nails having a mean length of 2.000 cms, with a standard deviation of 0.070 cms.
For a sample of 35 nails, the mean length is 2.025 cms. The correct conclusion at a 10% significance level if the test statistic
value is 2.113, is:
O A. Fail to accept the null hypothesis. The machine produce nails with mean length of 2.000 cms.
O B. Do not reject null hypothesis, the machine does not produce nails with mean length of 2.000 cms.
O C. Do not reject null hypothesis, the machine produce nails with mean length of 2.000 cms.
O D. Fail to accept the null hypothesis. The machine does not produce nails with mean length of 2.000 cms.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6e2616ca-e5f6-409e-8821-54dcdb505cdc%2Fd30e8830-55ef-4105-aed2-22bd4c4a475e%2Fl7uvdze_processed.png&w=3840&q=75)
