    The given reports the P value testing the null hypothesis that the overall slope is zero, the best fit value of the slope is 0.00. The P value answers the question: If the true slope is zero, what is the chance that the slope will be further from zero than the observed slope due only to random sampling. Since the observed slope is zero, there is almost a 100% chance of obtaining a slope that is further than zero than observed! So the P value is greater than 0.99, as high as a P value can be. Some

    DISCUSSION ABOUT STATISTICAL ANALYSIS AND RESULTS; Statistical analysis two independent sample tests compare the mean of the randomised case-control group. To find the significant difference between the two groups, data collections are mean value, so t test is the suitable test to compare the mean value of the two groups in normal distributed data (Menz, 2004). Result of the t test shows body mass index significant p value .005 less than .05 and the mean value of the BMI in case group greater than
