Aleasing firm claims that the mean number of miles driven annually, u , in its leased cars is less than 12800 miles. a random sample of 50 cars leased from this firm had a mean of 12499 annual miles driven. it is known that the population standard deviation of the number of miles driven in cars from this firm is 3140 miles. is there support for the firm's claim at the 0.05 level of significance?

Prove (a) cosh2(x) ā sinh2(x) = 1 and (b) 1 ā tanh 2(x) = sech 2(x). solution (a) cosh2(x) ā sinh2(x) = ex + eāx 2 2 ā 2 = e2x + 2 + eā2x 4 ā = 4 = . (b) we start with the identity proved in part (a): cosh2(x) ā sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 ā sinh2(x) cosh2(x) = 1 or 1 ā tanh 2(x) = .
