The U.S. government would like to predict the country's population for the next census scheduled for 2030. To aid their forecasting, the U.S. census bureau has models that predict the number of children that will be born over the next 8 years based on the current census data. One key factor that aids their prediction is a presumed negative correlation between the number of siblings a person had while growing up and the number of children they will have. Using the sample data provided in the table below, compute a one-tailed Pearson correlation with = .05, and determine whether this presumption is warranted.
Person | Siblings | Children |
A | 6 | 1 |
B | 0 | 4 |
C | 4 | 0 |
D | 2 | 2 |
E | 2 | 1 |
F | 1 | 2 |
Answer choices
There is not enough information to make a statistical decision.
No. Siblings and children are positively correlated, with SP = 21, r(4) = 0.84, p > .05.
Yes. Siblings and children are negatively correlated, with SP = -11, r(4) = -0.74, p < .05.
No. Siblings and children are not correlated, with SP = 5, r(4) = -0.27, p > .05.
Yes. Siblings and children are negatively correlated, with SP = -18, r(4) = -0.81, p < .05.
Yes. Siblings and children are negatively correlated, with SP = 23, r(4) = -0.93, p < .05.
