The null distribution of Student’s t changes with the degrees of freedom: When df = 1, the distribution is strongly leptokurtic , meaning the probability of extreme values is greater than in a normal distribution. WebZ-tables can help you find the critical z-values for a z-test. To find these values, you need to know the significance level and whether you’re performing a one- or two-tailed test. In a hypothesis test, the results are statistically significant when the test statistic exceeds a critical value. Z-tests use z-values for its test statistic. fm whatsapp for windows 10

"WebAboutTranscript. 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. " - Finding critical value in statistics
