Null hypothesis: posits that there is no effect of one variable over another variable. Alternative hypothesis: posits that here is indeed an effect of one variable over the other variable. Statistical tests estimates the probability of being wrong when we reject the null hypothesis. Low probability, we reject the null hypothesis and favour the alternative hypothesis. 5% (0. 05) probability of wrongfully rejecting the null hypothesis. The larger the p-value, the larger the difference between the expected and observe value. P<0. 05, results are statistically significant so we confidently say there is a statistical effect in data.
