a teacher gathered data about the number of hours her students spent studying for a test and their resulting test grades. she found that on average, for every 30 minutes studied, the grade increased by 8 points. which statements about this relationship are true? check all that apply. the data set would have a linear association. the data set would have a nonlinear association. the data set would have a positive correlation. the data set would have a negative correlation. every student earns 16 more points for each additional hour they study. students that study more tend to earn better grades on the test.

Answer

Answer:

  • The data set would have a linear association.
  • The data set would have a positive correlation.
  • Students that study more tend to earn better grades on the test.

Explanation:

Step1: Analyze linear - nonlinear

Since for every 30 minutes studied, grade increases by 8 points (constant rate), it's linear.

Step2: Analyze positive - negative correlation

As study time increases, grade increases, so positive correlation.

Step3: Interpret overall relationship

More study time is associated with better grades.
