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 statisticvalue 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.

Question

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.
