Question

Consider the sample regressions for the linear, the logarithmic, the exponential, and the log-log models. For each of the estimated models, predict y when x equals 70. (Do not round intermediate calculations. Round final answers to 2 decimal places.)

	Response Variable: y		Response Variable: ln(y)
	Model 1	Model 2	Model 3	Model 4
Intercept	18.36	−6.68	1.47	1.01
x	1.67	NA	0.05	NA
ln(x)	NA	29.69	NA	0.94
se	23.72	19.55	0.13	0.11
