Diffrence between correlation and regression analysis. Raw materials are used in the production od synthesis and fiber are stored in a place which has no humidity control. Measurement of relative humidity in the storage place and the moisture content of a sampleof a raw materials (both in percentage) on 10 days yeilds the following results.

1. Compute correlation coefficiet between humidity and moisture content and interpret the result.
2. Find the regression equation of moisture content on humudity.
3. Estimate the moisture content if humudity is 45%
4. Interpreat the value of regression coefficient.
