T test p value greater than 0.05

WebThe p-value is a value that is used as part of a hypothesis test. Assuming that the null hypothesis is true, the p-value is the probability of obtaining test results that are at least as extreme as the observed results. It takes on values between 0 and 1 and indicates how likely it is to obtain a result based on random chance. WebThe p-value indicates how probable the results are due to chance. p=0.05 means that there is a 5% probability that the results are due to random chance. p=0.001 means that the chances are only 1 in a thousand. The choice of significance level at which you reject null hypothesis is arbitrary. Conventionally, 5%, 1% and 0.1% levels are used.
