Zeros on a roulette wheel: we now wish to make a more sophisticated estimate of the number of zeros on a roulette wheel without looking at the wheel. we will do so with bayesian inference. recall that when a ball on a roulette wheel falls into a non-zero slot, odd/even bets are paid, when it falls into a zero slot, they are not paid. there are 36 non-zero slots on the wheel. we assume that the number of zeros is one of {0,1,2,3). we assume that these cases have prior probability 0.1,0.2,0.4,0.3). (a) writen for the event that, in a single spin of the wheel, an odd/even bet will not be paid (equivalently, the ball lands in one of the zeros). write z for the number of zeros in the wheel. what is p(n|z) for each of the possible values of z (i. e. each of {0,1,2,3})? (b) under what circumstances is p(z = 0 observations) not 0? (c) you observe 36 independent spins of the same wheel. a zero comes up in 2 of these spins. what is p(zlobservations)?

Suppose a man is heterozygous for heterochromia, an autosomal dominant disorder which causes two different‑colored eyes in an individual, produced 25‑offspring with his normal‑eyed wife. of their children, 15 were heterochromatic and 10 were‑normal. calculate the chi‑square value for this observation.

Astudy was interested in determining if eating milk chocolate lowered someone's cholesterol levels.ten people's cholesterol was measured. then, each of these individuals were told to eat 100g of milk chocolate every day and to eat as they normally did. after two weeks, their cholesterol levels were measured again. is there evidence to support that their cholesterol levels went down? how should we write the alternative hypothesis? (mud = the population mean difference= before - after)a. ha: mud = 0b. ha: mud > 0c. ha: mud < 0d. ha: mud does not equal 0
