The following times to failure in hours were observed in an experiment where 14 units were tested until eight of them have failed:
80, 310, 350, 470, 650, 900, 1100, 1530
(a). Assuming that the units have a constant failure rate, calculate a point estimate of the failure rate.
(b). Calculate a 95% one-sided confidence interval of the failure rate.

Over a 2 week period a study of junction failures was conducted. The junctions exposed to heat cycling repeatedly until they failed. Five test stations were in place and failed units were replaced immediately during test. The tests ended at a predetermined time. The data below are failure times in hours. The values marked with an asterisk (*) are censored. Utilizing Matlab or spreadsheet to compute values and make plots. 23, 278* , 73, 263*, 156*, 33, 22*, 72, 91,...

Twelve different video games showing product placement were observed and the duration times of game play (in seconds) were recorded and found to have a normal distribution. The design of the study justifies the assumption that the sample can be treated as a simple random sample. Given a sample standard deviation of 60.9 seco, use the sample data to construct a 99% confidence interval estimate of (greek letter sigma), the standard deviation of the duration times of game play.
