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

Question

Click the icon to view the table.

a. Find the probability of getting exactly 1 girl in 8 births.

nothing

(Type an integer or a decimal. Do not round.)

b. Find the probability of getting 1 or fewer girls in 8 births.

nothing

(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)?

Since the probability of getting more than 1 girl is the complement of the result from part (b), this is the relevant probability.

Since getting 0 girls is an even lower number of girls than getting 1 girl, the result from part (b) is the relevant probability.

Since the probability of getting 0 girls is less likely than getting 1 girl, the result from part (a) is the relevant probability.

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.

No, since the appropriate probability is less than 0.05, it is not a significantly low number.

Yes, since the appropriate probability is greater than 0.05, it is a significantly low number.

No, since the appropriate probability is greater than 0.05, it is not a significantly low number.

Yes, since the appropriate probability is less than 0.05, it is a significantly low number.
