In a test of significance, p value is 0.023 the observed difference in study can be considered as -
Ans is 'b' i.e. Null hypothesis rejected and the study accepted By convention, a Null hypothesis is rejected when P S 0.05, i.e. the difference between two samples is true (statistically significant) and not by chance p 50.05 is considered as statistically significant. In the question p = 0.023 (less than 0.05) ---> Null hypothesis is rejected and the difference seen in study is true (study is accepted). Also know P value 0.05 is considered as statistically significant P value 5 0.001 is considered as statistically highly significant.
