You may need to use the appropriate appendix table or technology to answer this question.The U.S. Energy Information Administration (US EIA) reported that the average price for a gallon of regular gasoline is $2.94. The US EIA updates its estimates of average gas prices on aweekly basis. Assume the standard deviation is $0.25 for the price of a gallon of regular gasoline and recommend the appropriate sample size for the US EIA to use if they wish to reporteach of the following margins of error at 95% confidence. (Round your answers up to the nearest whole number.)(a) The desired margin of error is $0.10.(b) The desired margin of error is $0.06.(c) The desired margin of error is $0.04.

The information provided in the question is as follows :-Population standard deviation and…
