Did you mean: mr. montanari has noticed that there is a wide range of grades that students get on tests, even though they are all in the same class. he wonders whether students, who study for 20 minutes per night, every night, get higher scores on tests or not. mr montanari wants as many kids to be successful as possible. pleas him write a hypothesis about this problem

Our hypothesis is based on the performance of students in the tests given the amount of time they studied last night before the exam. The testable version of the hypothesis will be whether the students studying 20 minutes per night, every night, get higher scores on the test. To test the hypothesis, Mr. Montanari needs to do a survey of his students to find out the time of study and the duration of study before the examinations. By analysing and interpreting the data, he can either reject or accept the hypothesis. Hypothesis will get rejected:

1.  when there's at least one case where the individual might have not studied before the examination but still managed to score the highest.

2. when there's at least one case where the individual might have studied in the day time but still managed to score the highest.

3. when there's at least one case where the individual might have studied for 20 minutes per night for every night but got an average score in the test.
