What is your conclusion regarding Ho?
Do not reject Ho. There is not sufficient evidence at the x = 0.01 level of significance to conclude that there is a
difference in the measurements of velocity between device A and device B.
c) Construct a 99% confidence interval about the population mean difference. Compute the difference as device A minus
device B. Interpret your results.
The confidence interval is ().
