Humidity influences evaporation as a result the solvent bala

Humidity influences evaporation, as a result, the solvent balance of water-reducible paints during sprayout is affected by humidity. A study is conducted to examine the relationship between % humidity (X) and solvent evaporation by % weight (Y ). Summary statistics for the data are: Xx = 1314.90 Py = 235.70 Xxy = 11,824.44 Xx 2 = 76,308.53 Py 2 = 2286.07 n = 25 Using these summary statistics:
1. Find the least-squares estimates ˆ 0 and ˆ 1.
2. Compute the 95% confidence intervals for 0 and 1.
