e. Construct a 95% confidence interval estimate for the mean property tax . Explain the practical, business-related meaning of this confidence interval.
f. Construct a 99% confidence interval estimate for the mean property tax. Explain the practical, business-related meaning of this confidence interval.
g. Comment on the effect that changing the level of confidence had on your answers in (e) and (f). Explain how your confidence intervals relate to to a researcher’s “alpha” level.
