Psychology students at BYU-Idaho conducted a survey that compared GPA levels and number of absences among students in a certain class. The students compiled the following results:

Student Absences GPA
Student 1 2 2.77
Student 2 1 3.76
Student 3 7 2.30
Student 4 6 3.11
Student 5 2 3.73
Student 6 2 3.03
Student 7 6 3.43
Student 8 6 2.48
Student 9 12 2.28
Student 10 0 3.56

Based on the survey results, what would the forecasted GPA be for a student with 3absences? (Display your answer to two decimal places.)

What is the r-value (correlation coefficient) for this set of data? (Display your answer to two decimal places. If you get a negative number then put a minus sign before your number.)

The correlation coefficient (from the previous question)indicatesthat as the number of absences goes DOWN, GPA tends to go:

The psychology students determined that the magnitude of acorrelation coefficient(whether positive or negative) is considered strongif it is0.70 or more, moderate if it is between 0.40 and 0.69, and weak/noneif it is below 0.40. Based on your analysis, the correlationbetween absences and GPA is:
