3. In an experiment to calibrate The British Imperial Yard against The Meter, one hundred measurements gave an average of 91.4402 cm. The standard deviation was determined to be 800 microns. (A micron = 10^-6 meter, where one meter equals 100 cm). Answer the following questions as appropriate. The 85%-confidence interval for the exact length of the Imperial Yard in centimeters is from ___________ to ______________. (Be sure to use a graph of Area Under the Standard Normal Distribution Curve, SNDC if applicable)
