The Fairchild Republic A-10 Thunderbolt is a single-seat, twin turbofan engine, straight wing jet aircraft developed by Fairchild-Republic for the United States Air Force (USAF). This jet is estimated to get an average of 50 mpg of jet fuel in normal weather condition. However, this milage varies on mission t mission. It’s been observed that, if this aircraft is deployed in the middle east, the milage drops to 40 MPG on an average and if it’s been deployed in the Antarctic, the milage drops to 70 MPG. Suppose that this aircraft’s mean milage is what it gets in normal weather condition and has a standard deviation of 5.9 mpg. Find the probability that the average miles per gallon for 38 randomly selected A-10 Thunderbolt is a) More than 515
b) Between 48 and 51
c) Less than 53
d) Greater than the population mean by 25 or more
