Question: A company manufactures steel bolts that continuously feed an assembly line downstream. Historically, the thickness of these bolts follows a normal distribution with a standard deviation of 1.6 mm. A recent random sample of 10 observations yielded these values of thickness, in mm:

  1. Construct a 95 % confidence interval for the true mean thickness.
  2. Find the number of observations, n, required to estimate the true mean thickness to within \(\pm \) 0.2 mm using a 95% confidence interval.
