Consider the following sample regression function explaining research and development intensity: rms = 2.013 + 00003080163 + 00000000705011.\"2 (.429) (00014) (0000000037) n = 32, R2 = .1484 _...-I-I-._.__ a) According to this data, 5331:\" is approximately equal to _? b) Draw a sketch of the shape of this regression function with rdintens on the vertical axis and sales on the horizontal axis. Label the numerical value at the intercept. Calculate and label the numerical value of rdintens and sales at the turnaround point. (3) Consider the null hypothesis H0 : 5mm: = 0 against the alternative H1 : 3501332
