Defective electronics: A team of designers was given the task of reducing the defect rate in the manufacture of a certain printed circuit board. The team decided to reconfigure the cooling system. A total of 988 boards were produced the week before the reconfiguration was implemented, and 263 of these were defective. A total of 859 boards were produced the week after reconfiguration, and 178 of these were defective. Part: 0 / 2 Part 1 of 2 (a) Construct a 90% confidence interval for the decrease in the defective rate after the reconfiguration. Use tables to find the critical value and round the answer to at least three decimal places. A 90% confidence interval for the decrease in the defective rate after the reconfiguration is
