A student is designing an experiment about the factors that affect math grades. Which statement best represents a possible hypothesis for this
experiment?
O A. I think practicing math problems is the most important factor in a
student's math grade.
OB. If students spend at least 1 hour per night studying math, then
they will get a grade of 85 or higher.
C. Students who study more get higher math grades.
O D. Steve studied math for 1 hour every night and got a grade of 87.

B. If students spend at least 1 hour per night studying math, then  they will get a grade of 85 or higher.

Explanation:

A hypothesis is defined as a tentative or predictions or an educated guess of scientific questions. A hypothesis is always done before performing an experiment.

The correct hypothesis for the given experiment will be "If students spend at least 1 hour per night studying math, then  they will get a grade of 85 or higher" because it has an if-then statement which is a conditional statement where statement after "if represents hypothesis" and "then represents conclusion".

Hence, the correct answer is "B. If students spend at least 1 hour per night studying math, then  they will get a grade of 85 or higher."
