explain each answer. thumbs up after the task.

Directions: Read the situation and answer the succeeding questions below. Ms. Maria is a Practical Research teacher who wanted to investigate if the number of hours spent by students in studying has something to do with their achievement score. Ten students were randomly selected and asked how many hours they spent in studying before they took the exam in Practical Research. To determine students' achievement score, the teacher administered a 50- item exam which was validated by experts in the field of research. You already solve the value of r in activity 1? 1. What is the value of r (refer to activity 1)? 2. What is its corresponding degree of relationship? 3. Since you already know the value of r and its corresponding degree of relationship, what is the connection of hours spent in studying to the achievement score of the students?Activity 1: Test the Relationship Directions: Analyze the given situation and follow the instructions below. Ms. Maria is a Practical Research teacher who wanted to investigate if the number of hours spent by students in studying has something to do with their achievement score. Ten students were randomly selected and were asked if how many hours they spent in studying before they took the exam in Practical Research. To determine students' achievement score. the teacher administered a - item exam which was validated by experts in the eld of research. Below are the scores of the ten students. Use Pearson*s Product Moment correlation coefcient [r] to nd the relationship between the independent variable (hour spent in studying] to the dependent variable (achievement score}. Complete the table below and follow the steps in solving Pearson's Product Moment correlation coefcient {r}. Round off your answer into two decimal places.
