It has been a long time since I looked at t-tests, so I don't remember the details very well. I would suggest that you need to check your procedure and make sure you are clear on what the p value represents.

WebSo for a z-score of -2, with a p-value of 0.5, that gives (1- 0.9798) = 0.0202.

We compare a P-value to a significance level to make a conclusion in a significance test. Given the null hypothesis is true, a p-value is the probability of getting a result as or more extreme than the sample result by random chance alone. If a p-value is lower than our significance level, we reject the null hypothesis. WebA p-value is the probability that, if the null hypothesis were true, we would observe a statistic at least as extreme as the one observed. To calculate a p-value we use the appropriate … dawn mission ffxi
