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. 0.017

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

c. Which probability is relevant for determining whether 1 is a significantly low number of girls in 8births: the result from part(a) or part(b)?

d. Is 1 a significantly low number of girls in 8births? Why or whynot? Use 0.05 as the threshold for a significant event.
