The accompanying table descnbes results from groups of8 births from 8 different sets of parents The random variable x represents the number ofgirls among 8 children Complete parts (a) through (d) below. a Click the icon to View the table a. Find the probability of getting exactly 6 girls in 8 births. 0.102' (Type an integer or a decimal. Do not round.) ProbabiIity distribution for x b. Find the probability of getting 6 or more girls in B births. (1131' (Type an integer or a decimal. Do not round ) Number of Girls x o c. Which probability is relevant for determining whether 6 is a signicantly high number of girls in 8 births: the result from part (a) or part (b)? J' A. The result from part b, since it is the complement of the result 0t part a. B. The result from part a, since it less than the probability of the given or more extreme result C. The result from part a. Since it is the exact probability being asked * D. The result from part b, Since it is the probability of the given or more extreme result. 1 Z 3 4 5 6 7 8 d. Is 6 a signicantly high number olgirts in 8 births? Why or why not? Use {3.05 as the threshold fora signicant event A. Yes, since the appropriate probability is less than 0.05, it is a Signicantly high number * B. No, since the appropriate probability is greaterthan 0.05, it 'is not a signicantly high number 9'0. No, since the appropriate probability is less than 0.05, it is not a significantly high number. D. Yes, since the appropriate probabdity is greater than 0.05, it is a signicantly high number
