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. E Click the icon to view the table. a. Find the probability of getting exactly 6 girls in 8 births. (Type an integer or a decimal. Do not round.) b. Find the probability of getting 6 or more girls in 8 births. (Type an integer or a decimal. Do not round.) 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)? O A. The result from part a, since it is the exact probability being asked. O B. The result from part b, since it is the complement of the result of part a. Probability Distribution for x OC. The result from part a, since it less than the probability of the given or more extreme result. O D. The result from part b, since it is the probability of the given or more extreme result. Number of Girls x 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. P(x) 0.004 O A. Yes, since the appropriate probability is greater than 0.05, it is a significantly high number. 1 0.012 0.107 O B. Yes, since the appropriate probability is less than 0.05, it is a significantly high number. 0.226 0.302 0.226 OC. No, since the appropriate probability is less than 0.05, it is not a significantly high number. 4 O D. No, since the appropriate probability is greater than 0.05, it is not a significantly high number. 6 0.107 0.012 O 004
