Using traditional methods, it takes 101 hours to receive a basic flying license. a new license training method using computer aided instruction (cai) has been proposed. a researcher used the technique with 140 students and observed that they had a mean of 100 hours. assume the standard deviation is known to be 6. a level of significance of 0.01 will be used to determine if the technique performs differently than the traditional method. is there sufficient evidence to support the claim that the technique performs differently than the traditional method?

An airplane consumes fuel at a constant rate while flying through clear skies, and it consumes fuel at a rate of 64 gallons per minute while flying through rain clouds. let c represent the number of minutes the plane can fly through clear skies and r represent the number of minutes the plane can fly through rain clouds without consuming all of its fuel. 56c+64r < 900056c+64r< 9000 according to the inequality, at what rate does the airplane consume fuel while flying through clear skies, and how much fuel does it have before takeoff? the airplane consumes fuel at a rate of gallons per minute while flying through clear skies, and it has gallons of fuel before takeoff. does the airplane have enough fuel to fly for 60 minutes through clear skies and 90 minutes through rain clouds?
