Delco Products, a division of General Motors, produces commutators designed to be 18.810 mm in overall length. (A commutator is a device used in the electrical system of an automobile.) The following sample of 35 commutators was taken while monitoring the manufacturing process: (The sample does/does not provide sufficient evidence... enter this along with your statement)

Is there sufficient evidence to reject the claim that these parts meet the design requirements "mean length is 18.810" at the = 0.01 level of significance?

Because your data is incomplete, I have assumes a sample mean of 18.82 and a standard deviation of 1.2
You'll have to find the true mean and standard deviation of your data and follow the procedure. The result may vary.
H0: mu = 18.81
HA: mu not = 18.81
Sample mean 18.82 (assumed value: compute and replace)
Standard deviation = 1.2 (assumed value : compute and replace)
Standard error of mean = sd / sqrt(n)
SE = 1.2/5.9161
Standard error of mean 0.2028
t = (xbar-mu) /se
t = (18.82-18.81) / 0.2028
t = 0.0493
If the computed t exceeds the critical t (with 34 degrees of freedom), reject H0 and conclude mean length is not 18.810. Otherwise, do not reject H0.
The critical t-value with 34 degrees of freedom with 0.01 level of significance is 2.728, so we do not reject H0.
