The accompanying table describes results from groups of 8 births from 8 different sets of parents. The random variable x represents the number of girls among 8 children. Complete parts (a) through (d) below. Click the icon to view the table. Probability distribution for X - X a. Find the probability of getting exactly 6 girls in 8 baths (Type an integer or a decimal Do not round.) Number of b. Find the probability of getting 6 or more girls in 8 births. Girls x P(x) O 0 0.002 (Type an integer or a decimal. Do not round) 0.036 0.105 C. Which probability is relevant for determining whether 6 is a significantly high number of girls in 8 births: the result from part (a) or part (b)? 0.229 0.256 O A. The result from part a, since it less than the probability of the given or more extreme result. 0.229 0. 105 O B. The result from part b, since it is the complement of the result of part a 0.036 O C. The result from part a, since it is the exact probability being asked. 0.002 O D. The result from part b, since it is the probability of the given or more extreme result. d. Is 6 a significantly high number of girls in 8 births? Why or why not? Use 0.05 as the threshold for a significant event Print Done O A. Yes, see the appropriate probability is less than 0 05, it is a significantly high number O B. Yes, since the appropriate probability is greater than 0 05, it is a significantly high number Time Remaining: 01 36: 11
