PROBLEMSTATEMENT
Is there any significant difference between the score of mathematics and the cut off value 30?
NULLHYPOTHESIS
There is no significant difference between the score of mathematics and the cut off value 30.
STATISTICS TO BE USED
Since the variable represents interval level of the measurement, and students’ mathematical skills in perspective of their teachers are to be compared with a cut off value of 30, one sample t-test will be used.

(sig. = .000)
The Null Hypothesis claiming no significant correlation between the cut off value of 30 and the mean level of mathematical skills of students is, therefore, rejected.
CONCLUSION
Mean level of students mathematical skills are significantly below (−ve sign indicates) the cut off value of 30.
