a. Find the probability of getting exactly 6 girls in 8 births. 0.102 (Type an integer or a decimal. Do not round.) b. Find the probability of getting 6 or more girls in 8 births. 0.126 (Type an integer or a decimal. Do not round.) 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 b, since it is the probability of the given or more extreme result. O B. The result from part b, since it is the complement of the result of part a. O C. The result from part a, since it less than the probability of the given or more extreme result. O D. The result from part a, since it is the exact probability being asked. 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. O A. Yes, since the appropriate probability is less than 0.05, it is a significantly high number. O B. No, since the appropriate probability is less than 0.05, it is not a significantly high number. OC. No, since the appropriate probability is greater than 0.05, it is not a significantly high number. O D. Yes, since the appropriate probability is greater than 0.05, it is a significantly high number.
