I need help with this please

An article in a reputable science journal presented data on the mole fraction solubility of a solute at a constant
temperature. Also measured are the dispersion x, and dipolar and hydrogen bonding solubility parameters X2 and
X3. A portion of the data is shown in the accompanying table. In the model, y is the negative logarithm of the mole
fraction. Complete parts (a) through (c) below.
Click the icon to view the mole fraction solubility data.
(a) Fit the model y; = ßo + ß1×1; +ß2×2; + ẞ3×3; + £; for i = 1, 2, ..., 20. Test Ho B₁ =ẞ₂ = ẞ3 = 0.
ŷ= -0.269 + (0.078) ×₁ + (0.025) x2 + ( − 0.036)x3
(Round to three decimal places as needed.)
Determine the alternative hypothesis.
