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. C 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 getting 0 girls is an even lower number of girls than getting 1 girl, the result from part (b) is the relevant probability. OB. Since the probability of getting 0 girls is less likely than getting 1 girl, the result from part (a) is the relevant probability. OC. Since the probability of getting more than 1 girl is the complement of the result from part (b), this is the relevant probability OD. Since the probability of getting 1 girl is the result from part (a), 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. OA. No, since the appropriate probability is greater than 0.05, it is not a significantly low number. OB. Yes, since the appropriate probability is less than 0.05, it is a significantly low number OC. No, since the appropriate probability is less than 0.05, it is not a significantly low number. OD. Yes, since the appropriate probability is greater than 0.05, it is a significantly low number.

Question
Transcribed Image Text: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.
**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)?
- **A.** Since getting 0 girls is an even lower number of girls than getting 1 girl, the result from part (b) is the relevant probability.
- **B.** Since the probability of getting 0 girls is less likely than getting 1 girl, the result from part (a) is the relevant probability.
- **C.** Since the probability of getting more than 1 girl is the complement of the result from part (b), this is the relevant probability.
- **D.** Since the probability of getting 1 girl is the result from part (a), 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.
- **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 less than 0.05, it is a significantly low number.
- **C.** No, since the appropriate probability is less than 0.05, it is not a significantly low number.
- **D.** Yes, since the appropriate probability is greater than 0.05, it is a significantly low number.
