Question 1
Sophia investigated the relationship between the number of hours two-year-old children spent in day care and the number of words each child could say. Day care is where children are looked after by carers other than their parents or relatives.
She recorded the average number of hours a week spent in day care and the number of different words the two-year-old children said in an hour.
The data gathered by Sophia is shown in Table 1.
