A graduate teaching assistant for an Introduction to Statistics course collected data from one of her classes to investigate the relationship between using the explanatory variable x = study time per week (average number of hours) to predict the response variable y = college GPA. For the 21 females in her class, the correlation was 0.42. For the eight males in her class, the data were as shown in the following table. Complete parts a through c below. Student 1 14 2.8 Study Time GPA 2 5 2.6 3 12 3.3 4 6 2.8 a. Use technology to obtain a scatterplot and the correlation coefficient. Use these to describe the relationship.
