PLEASE HELP ME WITH A AND B .

The technology underlying hip replacements has changed as these operations have become more popular (over 250,000 in the United States in 2008). Starting in 2003, highly durable ceramic hips were marketed. Unfortunately, for too many patients the increased durability has been counterbalanced by an increased incidence of squeaking. An article reported that in one study of 152 individuals who received ceramic hips between 2003 and 2005, 14 of the hips developed squeaking.

(a) Calculate a lower confidence bound at the 95% confidence level for the true proportion of such hips that develop squeaking. (Round your answer to three decimal places.)

Discussion: Types of Tax

After considering the "Types of Tax" PPT, please propose a general set of Income, Consumption, Wealth or other taxes at Federal, state or local level with rates for each which you consider would be best for the United States at this time. Please justify your choices by citing evidence from reliable outside sources. It is understood that this is only the revenue side of government (in Intro to Econ courses, taxes is included in Micro and spending in Macro -- go figure), but obviously if taxation changes, this has an impact on the spending side, at least in terms of whether there is a surplus or deficit.
