Raw material used in the production of a synthetic fiber is stored in a place that has no humidity control. Measurements of the relative humidity and the moisture content of samples of the raw material (both in percent-ages) on 12 days yielded the following results:

(a) Fit a least squares line that will enable us to predict the moisture content in terms of the relative humidity.
(b) Use the result of part (a) to estimate (predict) the moisture content when the relative humidity is 38 percent.
