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. Probability Distribution for x Number of Girls x P(x) 0 0.003 1 0.008 2 0.109 0.207 0.346 0.207 0.109 0.008 0.003 a. Find the probability of getting exactly 1 girl in 8 births. (Type an integer or a decimal. Do not round.) b. Find the probability of getting 1 or fewer girls in 8 births. (Type an integer or a decimal. Do not round.) c. Which probability is relevant for determining whether 1 is a significantly low number of girls in 8 births: the result from part (a) or part (b)? O A. Since the probability of getting 1 girl is the result from part (a), this is the relevant probability. O B. Since the probability of getting more than 1 girl is the complement of the result from part (b), this is the relevant probability. O C. Since the probability of getting 0 girls is less likely than getting 1 girl, the result from part (a) is the relevant probability. O D. Since getting 0 girls is an even lower number of girls than getting 1 girl, the result from part (b) is the relevant probability. d. Is 1 a significantly low number of girls in 8 births? Why or why not? Use 0.05 as the threshold for a significant event. O A. Yes, since the appropriate probability is less than 0.05, it is a significantly low number. O B. Yes, since the appropriate probability is greater than 0.05, it is a significantly low number. O C. No, since the appropriate probability is greater than 0.05, it is not a significantly low number. O D. No, since the appropriate probability is less than 0.05, it is not a significantly low number
