Question

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 6 girls in 8 births

b. Find the probability of getting 6 or more girls in 8 births 

c. Which probability is relevant for determining whether 6 is a significantly high number of girls in 8 births: the result from part (a) or part (b)? 

A. The result from part a, since it is the exact probability being asked. 

B. The result from part b, since it is the probability of the given or more extreme result. 

C. 6 0.116 The result from part a, since it less than the probability of the given or more extreme result. 

D. The result from part b, since it is the complement of the result of part a. 

d. Is 6 a significantly high 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 high number. 

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

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

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