We'll look at the Galton data frame from the mosaicData package: data(Galton) View(Galton) help(Galton) Here's a scatterplot of the heights of the mothers and the heights of their children: ***(YOU MUST CREATE THE SCATTERPLOT FROM INFO GIVEN) We would like to use the data to predict the height of a child from the height of her mother. As described in class and in the Course Notes, use the predict() function to predict the height of a child (the time of Galtons' study) if the child's mother was known to be 64 inches tall. Record your answer (without units) as a decimal number, correct to at least two decimal places.
