This problem uses the teengamb data set in the faraway package. fit a model with gamble as the response and the other variables as predictors. (a) predict the amount that men with average (given the data) status, income and verbal score would gamble along with an appropriate 95% confidence interval for the mean amount. (b) repeat the prediction for men with maximal values (for this data) of status, income and verbal score. which confidence interval is wider and why is the result expected? (c) fit a model with sqrt(gamble) as the response but with the same predictors. now predict the response and give a 95% prediction interval for an individual in (a). take care to give your answer in the original units of the response

How many zeros does the function f(x)=4x3-x2+1 have

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?
