The following question is multiple choice with 3 parts. I ONLY NEED the quick answer. I DO NOT need an explanation. I will give a great rating, thank you!

Question:

A Sociologiat i5 Studying the Size of rural Canadian familieS. A random Sample of familieS was taken and the number of children in each family Surveyed is noted for lowincome families and highincome familieS below. Which of the following represents a 95% confidence interval for the difference between the average number of childern between low-income and high-income families? O a (0.323 , 3.248) b (2.64 , 1.93) Oc (0.021 , 3.551) Od (-6.02 , 9.588)Which of the following is a correct interpretation of this interval? O a There is a 959% probability that we have not made a Type II error. Ob We are 959% confident that this interval captures the true difference in mean number of children for low-income families and high- income families O c 959% of the intervals constructed this way will contain the value 0. O d There is a 0.95 probability that the true difference in mean number of children for low-income families and high-income families Oe 959% of the time, the true difference in mean number of children for low-income families and high-income familiesIs there a difference between the two populations? Explain. Since the interval is positive, there is a larger mean number of children for low-income families. O a Since 0 is included in the interval, it is possible there is no difference between the two populations. Ob Since the interval is positive there is a larger mean number of children for high-income families. O c
