Scrapie is a degenerative disease of the nervous system. a study of the substance idx as a treatment for scrapie used as subjects 28 infected hamsters. fourteen, chosen at random, were injected with idx. the other 14 were untreated. the researchers recorded how long each hamster lived. they reported: thus, although all infected control hamsters had died by 94 days after infection (mean +/-sem=87.1 +/-1. idx-treated hamsters lived up to 108 days(mean +/- sem=98 +/-2.57). readers are supposed to know that sem stands for standard error of the mean.(a) for the group injected with idx, find: the mean, x bar= standard deviation, s=) for the untreated grop, find: the mean, x bar= standard deviation, s= include a step by step way to solve this using a ti-84 plus as well as any other methods that you have handy. this will me both understand it and save time. in advance.

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.)
