Conduct a hypothesis test to determine if the AZ100 drill holes are statistically significantly different from the hypothesized value of 3 centimeters. Use an alpha of .05, and assume the population standard deviation is unknown. What is the value of your test statistic?

To determine the precision of the two drills, you examine the variance in the sample data for the two samples.

Conduct a test of the hypothesis that the T2005 and the AZ100 are equally precise (that they have equal variances). What is the p-value of your hypothesis test?
