A random sample yielded the measurements 9.4, 10.6, 8.1, 12.2, 15.9, 9.0, 9.1, 10.0, 11.7, 11.0.

(a) Determine the sample mean and the 95% confidence interval for the population mean. (b) Determine the sample standard deviation and the 95% confidence interval for the population standard deviation.

(c) Display the data using a histogram and normal probability plots.

(d) Estimate the response that is exceeded 10%. Comment on the validity of the analysis and results.

(e) Create a process capability/performance report for a specification of 10.0  4.0. Comment on the validity of the analysis and results.
