Exercise 2.7.2: Proofs by cases - even/odd integers and divisibility. About Prove each statement. (a) If is an integer, then is odd. Solution (b) If integers and have the same parity, then is even. The parity of a number tells whether the number is odd or even. If and have the same parity, they are either both even or both odd. (c) If integers and where are consecutive, then they have opposite parity. (d) For integers and , if is odd, then is odd and is odd.

Cor d? ? me ? max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
