Answer:
Therefore, the 95% confidence interval for this sample is 0.099267 + 2*0.0125, which is ( 0.074267 , 0.124267 ) .
If we replicated the same study 100 times with different random samples and computed a confidence interval for each sample, we would expect 95% of the confidence intervals to contain the true slope of the regression line.

Case: Enron: Questionable Accounting Leads to CollapseIntroductionOnce upon a time, there was a gleaming office tower in Houston, Texas. In front of that gleaming tower was a giant “E,” slowly revolving, flashing in the hot Texas sun. But in 2001, the Enron Corporation, which once ranked among the top Fortune 500 companies, would collapse under a mountain of debt that had been concealed through a complex scheme of off-balance-sheet partnerships. Forced to declare bankruptcy, the energy firm laid off 4,000...
