To determine the average number of children in Ohio houses, the population is a) Houses in Ohio. This is because we are interested in the characteristic (number of children) within the specific context of houses in Ohio.

The type of variable for the average number of children in Ohio houses is b) Quantitative since it represents a countable number and would result in a numerical value that can be averaged.

To sample the data for the average number of children in Ohio houses, a a) Simple random sampling of houses in Ohio would be a clear and unbiased method. This involves selecting houses from the entire population of Ohio houses in such a way that each house has an equal chance of being chosen.
