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 0.94, 0.96, 1.02, 1.04, 1.01, 0.96, 1.02, 0.94, 1.06 D milimeters. Help them construct a 90% confidence interval for the population mean u. Click here to view page 1 of the standard normal distribution table.

Click here to view page 2 of the table of critical values of the t-distribution. With 90% confidence, population mean of the lengths will be between and (Round to three decimal places including any zeros.)
