10. Calibration of a device yields a least-squares-tted line of y : l + 10 x. Sample size used or the calibration was 17 and 52 = 4. Must Show All Your Work for Full Marks! Determine the range for the y values, for the 90% of the population, at x = 2, for a 0% condence limit. State your assumptions clearly. [10 points]
