... – My best estimate is that those “very likely” to patronize an upscale restaurant in the future, presently spend $281 dollars per month in a restaurant. In addition, I am 95% confident that the true population value falls between $267 and $297 (95% confidence interval). Therefore, Jeff Dean can be 9 ...

... 9. What is the equation for the regression line predicting number of doctors from population for the South region? A. Doctors = -338 + 2.3 pop B. Doctors = -255 + 83 pop C. Doctors = -172 + 2.3 pop D. Doctors = -255 + 2.3 pop 10. Based on this model, in which region is the slope of the regression li ...
