Question Help The random variable x represents the number of girls among 8 The accompanying table describes results from groups of 8 biths from 8diferent sets of parents. children. Complete parts (a) through (d) below EEB Click the icon to view the table c. Which probability is relevant for determining whether 1 is a significantly low number of girls in 8 births the resultfrom 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 rälevant 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 O C. Since the probability of getting 1 girl is the result from part (a), this is the relevant probability O D. Since the probability of getting more than 1 girl is the complement of the result from part (b) this is the relevant proba 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. Yes, since the appropriate probability is less than 0.05, it is a significantly low number O B. No, since the appropriate probability is greater than 0.05, it is not a significantly low number ° C. No, since the appropriate probability is less than 0 05 it is not a significantly low number O D. Yes, since the appropriate probability is greater than 0 05, itis a significantly low number Click to select your answer(s) Proctorio is sharing your screen search

Explanation / Answer

From given probability distribution table we get the following probabilities,

a) P(X = 1) = 0.023

The probability of getting exactly 1 girl in 8 births is 0.023

b) P(X <=1) = P(X =0) + P(X =1) = 0.003 + 0.023

=> P(X <=1) = 0.026

c) correct answer is,

C) Since the probability of getting 1 girl is the result from part(a) this is the relevant probability.

d) correct answer is,

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