Height and weight are two measurements used to track a child's development. the world health organization measureschild development by comparing the weights of children who are the same height and the same gender. in 2009, weightsfor all 80 cm girls in the reference population had a mean u = 10.2 kg and standard deviation 0 = 0.8 kg. weights arenormally distributed. x ~ n(10.2, 0.8). calculate the z-scores that correspond to the following weights and interpret them. a. 11 kgb. 7.9 kgc 122 kg

Afriend of mine is giving a dinner party. his current wine supply includes 10 bottles of zinfandel, 8 of merlot, and 11 of cabernet (he only drinks red wine), all from different wineries. (a) if he wants to serve 3 bottles of zinfandel and serving order is important, how many ways are there to do this? ways (b) if 6 bottles of wine are to be randomly selected from the 29 for serving, how many ways are there to do this? ways (c) if 6 bottles are randomly selected, how many ways are there to obtain two bottles of each variety? ways (d) if 6 bottles are randomly selected, what is the probability that this results in two bottles of each variety being chosen? (round your answer to three decimal places.) (e) if 6 bottles are randomly selected, what is the probability that all of them are the same variety? (round your answer to three decimal places.)
