Consider the situation of Case Study as: The diameters are as follows: 1.01, 0.97, 1.03, 1.04, 0.99, 0.98, 1.01, 1.03, 0.99, 1.00, 1.00, 0.99, 0.98, 1.01, 1.02, 0.99 centimeters. Once again the normality assumption may be made. Test the hypothesis that average of the diameter is greater than 1.00 with 5% level of significance? Discuss how they are different and why. Compute a 95% confidence interval on the mean diameter.
