Answer:
There is not enough information to know if there is a statistically significant difference in the number of children per family between the three countries.
Explanation:
There are other important information that are necessary in order to reach a decisive conclusion. This includes not just the f value only, but the alpha value, f critical value and the p-value after conducting the one way ANOVA.
Since we do not have information about the p value, as well as the alpha value there is no way to compare the effects of all the variables.
Therefore, no decision can be made by the Pediatrician without knowing what the p value is and the apha value is.
