Question 1011276: ) Raw material used in the production of synthetic fiber is
stored in a place which has no humidity control.
Measurements of the relative humidity in the storage
place and the moisture content of a sample of the raw
material (both in percentages) on 12 days yielded the
following results:
Humidity x 42 35 50 43 48 62 31 36 44 39 55 48
Moisture
content y 12 8 14 9 11 16 7 9 12 10 13 11
(i) Make a scatter plot to verify that it is reasonable to
assume that the regression of y on x is linear
(ii) Fit a straight line by the method of least squares,
(iii) Estimate the moisture content when humidity is 45%.
(iv) Determine the correlation coefficient. Answer by ikleyn(52794) (Show Source):
