Suppose we wish to use a linear model to predict the probability of acceptance (PACC) to college from GPA, SAT, ACT, scores. We have data from 100 students for the year 2022. Write the linear regression equation for this model.

a) PACC = β₀ + β₁GPA + β₂SAT + β₃ACT + ε
b) PACC = β₀ + β₁GPA + β₂SAT + ε
c) PACC = β₀ + β₁GPA + β₂SAT + β₃ACT + β₄Scores + ε
d) PACC = β₀ + β₁GPA + β₂SAT + β₃ACT + β₄Scores + β₅Year + ε
