You are able to locate five families in the world with 18-month-old toddlers who are learning both Japanese and Amharic simultaneously. Given that these are the only families that fit this qualification, therefore, these five families are your study population. You test the children to see how many words they can speak in Japanese. The results are listed in the following table: Toddler A P Calculate the mean for this population. B Complete the following table.
