An experiment is replicated to determine the variation in temperature for which a certain process takes place. Six readings were obtained and recorded in units of Kelvin. The readings recorded were 371.5, 370.3, 370.6, 371.2, 370.8 and 369.2. (i) Construct a 95% confidence interval for the true variance in temperatures. As a result obtain a 95% confidence interval for the true standard deviations in temperatures. E
