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)?
1
O A. Since the probability of getting more than 1 girl is the complement of the result from part (b), this is the relevant probability.
3
0.189
O B. Since the probability of getting 1 girl is the result from part (a), this is the relevant probability.
0.342
5
0.189
OC. Since the probability of getting 0 girls is less likely than getting 1 girl, the result from part (a) is the relevant probability.
6
0.119
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.
7
0.019
8
0.002
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 less than 0.05, it is not a significantly low number.
O B. Yes, since the appropriate probability is less than 0.05, it is a significantly low number.
Print
Done
OC. Yes, since the appropriate probability is greater than 0.05, it is a significantly low number.
O D. No, since the appropriate probability is greater than 0.05, it is not a significantly low number.
