(1 point) A Statistics professor assigned 10 quizzes over the course of the semester. He wanted to see if there was a relationship between the total mark of all 10 quizzes and the final exam mark. There were 205 students who completed all the quizzes and wrote the final exam. The standard deviation of the total quiz marks was 12, and that of the final exam was 18. The correlation between the total quiz mark and the final exam was 0.74. Based on the least squares regression line fitted to the data of the 205 students, if a student scored 25 points above the mean of total quiz marks, then how many points above the mean on the final would you predict her final exam grade to be? The predicted final exam grade is above the mean on the final. Round your answer to one decimal place, but do not round in intermediate steps.

She decides to first look at the relationship between the number of minutes customers spent talking on their phones and the amount of cellular data they use. She collects a month's worth of data on 300 customers who have smartphones with data plans. The mean monthly call time was found to be 247 minutes, and the mean amount of data consumed was found to be 433 megabytes. Based on the least squares regression line fitted to the data, it is found that for every minute increase in calling time, the data usage is expected to increase by 4.4 megabytes. Predict the amount of data used by a customer who spends 402 minutes on the phone. Do not round in intermediate steps. The predicted the amount of data used by a customer who spends 402 minutes on the phone is: (in megabytes, rounded to one decimal place)
