Question

The distribution of a critical dimension of the crankshaft produced by a manufacturing plant for a certain type of automobile engine is normal with mean m and standard deviation s = 0.02 mm. Suppose I select a simple random sample of four of the crankshafts produced by the plant and measure this critical dimension. The results of these four measurements are

200.01

199.98

200.00

200.01.

Based on these data, a 90% confidence interval for m is
