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 children. Complete parts (a) through (d) below. Click the icon to view the table. 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 or fewer girls is the result from part (a), this is the relevant probability. O B. Since the probability of getting 1 girl is the result from part (a), this is the relevant probability. OC. Since the probability of getting 1 or fewer girls is the result from part (b), this is the relevant probability. O D. Since the probability of getting 1 girl is the result from part (b), this 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. No, since the appropriate probability is greater than 0.05, it is not a significantly low number. B. Yes, since the appropriate probability is greater than 0.05, it is a significantly low number. O C. Yes, since the appropriate probability is less than 0.05, it is a significantly low number. O D. No, since the appropriate probability is less than 0.05, it is not a significantly low number.
