Use the following information to answer the next three questions. A scatterplot shows that city size of residence and number of children born to married couples has a decreasing linear trend, that is, on average, as the city size where a married couple lives increases the number of children that a married couple has decreases. The correlation is 0.767 and the regression equation is Predicted number of children = 5.2 - 0.08(city size) The variable "city size" was recorded in thousands of people. It should be noted that this model is only useful for relatively small cities with populations less than 65,000 people. 6. Use the regression equation to predict how many children a married couple will have if they live in a city with a population of 40,000 people. 7. State the slope and intercept of the regression line and explain each in context. Be sure to explain whether the intercept has a practical meaning in this context. 8. State the explanatory variable and the response variable
