Extracted text: Quality standards require the reporting of 90% confidence interval for the lengths of high-precision metal parts (in milimeters) which are approximately Normal. Quality inspectors sample a number of parts, whose lengths turn out to be 0.97, 0.94, 1.01, 1.04. 0.95, 0.96, 0.97, 0.97, 1.05 D milimeters. Help them construct a 90% confidence interval for the population mean p. Click here to view page 1 of the standard normal distribution table.
