Language | (X 28 | (X 23 | P P P | /Z/ = 1.91 | Since /Z/ < 1.96, the data are consistent with null hypothesis at 5% Level of significance. This means scores of the students under X |

Science | 13 | 8 | P Null hypothesis is valid | /Z/ = 1.36 | Since /Z/< 1.96, the data are consistent with null hypothesis at 5% level of significance. This means 8 students out of 13 (Thirteen) students who did well in school test, did well in test of reference, while the rest number of students failed to score 70% and above. |

Math | 15 | 5 | P₁ ≠ P₂ | /Z/ = 2.95 | Since /Z/ > 1.96, the data are not consistent. This means that the number of students scoring 70% and above in Mathematics in our test are not in parity with those in Math of their school test. |
