Check My Work (2 remaining) The U.S. Energy Information Administration (US EIA) reported that the average price fora gallon of reqular gasoline is $3.89. The US EIA updates its estimates of average gas prices on a weeldy basis. Assume the standard deviation is 0.24 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 report each of the following margins of error at 95% confidence. Round up to the net whole number. a. The desired margin of eor is $0.11. The appropriate sample size is b. The desired margin of error is $0.07. The appropriate sample size is c. The desired margin of error is $0.05. The appropriate sample size is
