Answer:
Explanation:
Two groups were tested to compare their speed at working math problems.
Aim/Objective of experiment:
To test their speed (each group and then compare) at working math problems
Control Group:
The group of students computing math problems without a calculator
Experimental Group:
The group of students computing math problems with a calculator
Statistical Hypothesis:
Null hypothesis: Both the control and the experimental group worked math problems at the same pace or speed
Alternative hypothesis: The experimental group worked math problems with a greater speed than the control group
This hypothesis is derived from the thought or knowledge that calculators help solve math problems faster. Your hope would be to refute the null hypothesis and accept the alternative hypothesis; after testing.
