Question

accompanying table doscnbes resuits from groups ofl 8 births from 8 dferent sets of parents The random variable x represents the number of girls among B children Compiede parts (a) trough (d) below Probability Distribution for x a Find the probability of geting exactly 6 grts in 8 birth (Typo rteger or a decenal Donot round) b. Find the probablity of getting 6 or more girls in B berth (Type an integer or a decimal Dio not round or determining whether 6 is a signsfcantly high number of grts in 8beths tho es trom part (a) or part b) O A Snce te probsbity of getting 7 or 8 girts is Hess holy than gotting 6 girts, the resull trom pat (a) is the O C. Snce the peobabulity of geting6geis is the rosult rom part (ai, this is the relevant probablity O D. Since probability of getting 7 or D girts inclaos getting 6 gris the resut fom pat ) evant probabity the peobability of geting lewer than 6 gris is the complement of the result from part () this is the relevart probay dis 6 sgntcantly hun rumee, of gr% in B turths? why or why non use 005 as the Preshold for a Print Done A Yes,snce the appropriate probabiity is less than 0 05 t s a sgnfcantly high be snce the appropriate probabMy greater than 0 05,a s nicantly high rumter seco tho appropriate probabley s greater ban o os til not a ugnkanty huh hnter snce me appropriate probabity is less tan 005,.snt a spacathy hgh, ranter C OD

Explanation / Answer

Solution:-
a) P(X = 6) = 0.101

b) P(X <= 6) = P(6)+P(7)+P(8) = 0.101+0.006+0.003 = 0.11

c) option B.
