Please provide me an answer with explanations.

Heart Rate Age Weight Height (bpm) (yrs) (Ib) (in) 73 23 175 63 59 35 201 63 63 21 263 68 75 48 144 70 102 37 232 61 106 44 225 59 103 52 140 70 93 41 244 63 70 26 118 73 105 57 150 65 66 30 181 74 68 45 103 72 68 39 105 75 106 56 154 60 68 23 174 71 57 23 103 70 63 25 103 75 67 45 141 62 88 29 164 71 67 29 150 67 115 37 223 69 89 51 158 68 94 43 185 69 96 53 133 70 94 50 227 69 119 57 165 65 100 44 139 58 107 56 231 66 89 43 149 60 95 51 208 59a) Find the multiple regression equation using all three explanatory variables. Assume that x1 is age, x2 is weight and x3 is height. Give your answers to 3 decimal places. Y = age + weight + height b) At a level of significance of 0.05, the result of the F test for this model is that the null hypothesis v rejected. c) The explanatory variable that is most correlated with heart rate is: O age O weight Oheight d) The explanatory variable that is least correlated with heart rate is: O age O weight O height e) The value of R for this model, to 3 decimal places, is equal to f) The value of s for this model, to 3 decimal places, is equal to g) Construct a new multiple regression model by removing the variable height. Give your answers to 3 decimal places. The new regression model equation is: Y = + age + weight h) In the new model compared to the previous one, the value of R (to 3 decimal places) is: O increased decreased O unchanged i) In the new model compared to the previous one, the value of s (to 3 decimal places) is: increased decreased O unchanged
