Circle the single best answer. The association is "real", that is not likely due to chance. • The association is "random", that is likely due to chance. • There is a cause-and-effect relation between the variables. • There is no cause-and-effect relațion between the variables. 14

Answer 1

From the given information,

a.

We know that,

Factor is significant if its p-value is less than level of significance (0.05)

Hence,

The required significant factors are,

1) Mother's BMI

2) Number of siblings

3) Family divorce

This all factors have p-value < 0.05

Hence, these are significant factors.

b.

Association means There is a cause-and-effect relation between the variables.
