Table of contents What is p-value? How do I calculate p-value from test statistic? How to interpret p-value How to use the p-value calculator to find p-value from test statistic How do I find p-value from z-score? How do I find p-value from t? p-value from chi-square score ...
WHY to have a t statistic here in a hypothesis test? We need to know that whether the deviation from the population parameter is large enough to warrant the rejection of null hypothesis. As with all testing, the answer depends on the significance level of the test. Butwe cannot carry out ...

是的，当你做t-test的时候，p-value跟你的t-statistic 的值是对应的。因为p－value的意义是取到t-statistic的概率。
p-value :A p-value is the probability of obtaining a test statistic at least as extreme as the one that was observed, assuming that Ho is true. 什么是 p 值呢?它是一个概率值。如果零假设为真,现有的检验统计量出现的概率就是 p-value。
Step 1:Calculate the test statistic value (x) using the following formula, Test statistic = (x̄ -μ) / (s/√n) We can write the above formula in the Excel format as follows: =(B9–B10) / (B11/SQRT(6)) Enter the above formula in cellB12and press“Enter”.As a result, Excel...
Step 3: Calculate the test statistic using: z=p^−p0p0⋅q0n p ^ = p0= q0=(1−p0) n= Step 4:Using the found test-statistic and a Normal distribution table or calculator, find the corresponding p-value. What are a Test-Statistic and P-value?
p_value: The p-value is the probability, assuming the null hypothesis is true, that we obtain a value at least as large as our test statistic from our sample data. Significance Level: The significance level captures the risk of making a mistake by rejecting t...
Answer to: Use the given information to find the P-value: The test statistic in a right-tailed test is z = 1.43. By signing up, you'll get...
Answer to: Use a table of t - values to estimate the p - value for the specified one - mean t - test. Right - tailed test, n = 23, t = 1.581. By...
