Hi, these are some exam questions from a passed exam paper for my Applied Regression module could you help with correct instructive solutions so i can prepare for my exam please?

A]. The simple linear regression equation can be written as E[Y] = 39 4 x. The symbol Y represents the {a} estimated or predicted response {b} estimated intercept {c} estimated slope {d} explanatory.r variable (e) response variable A2. In a simple linear regression model, 1"; = .15}; +311} +E,- {1' = 11 2,. um}, the term ,3\". represents the {a} response {b} intercept {c} slope {d} explanatoryr variable A3. In simple linear regression, sometimes we need to perform a two-sided hypothesis test involving the slope .51 to determine whether there is sufcient evidence to infer that it is different from zero. The alternative hypothesis is stated as: {a} Hoiot'e {h} Ho:.51= {'3} Hoin=u {d} None of these choices
