The number of tails:We need to know whether our t-test is one-tailed or two-tailed because we will use the respective one-tail or two-tail row to mark the alpha level. The alpha levels are listed at top of the table (0.50, 0.25, 0.20, 0.15…for the one-tail and 1.00, 0.50, 0....
T-Distribution Table (One Tail). For more info on the parts of the t table, including how to calculate them, see: degrees of freedom and alpha level.
Step 2: Look up the df in the left hand side of the t-distribution table. Locate the column under your alpha level (the alpha level is usually given to you in the question). For more detailed steps, including a video, see: t score formula. Uses The T Distribution (and the associated...

通过把所得到的统计检定值,与统计学家建立了一些随机变量的概率分布(probability distribution)进行比较,我们可以知道在多少%的机会下会得到目前的结果。倘若经比较后发现,出现这结果的机率很少,亦即是说,是在机会很少、很罕有的情况下才出现;那我们便可以有信心的说,这不是巧合,是具有统计学上的意义的(用统计学的...
Step 3:Based on the significance level you chose and the type of tail, you find the critical t-statistics by either looking at a t-distribution table or use a calculator or Excel. Then, you clearly state your rejection region Step 4:You compute the t-statistic using the formula specified...

Describe the relationship between the Z table and the standard normal distribution table. Formulate a probability statement to determine the value of z so that the area under the standard normal curve in the left tail is 0.0377. If a population distribution has an average...

Each type has one of the asymmetry parameters fixed to 1, so that the corresponding copula density is either left- or right-skewed (relative to the main diagonal). In the manual we will call these two new copulas "Tawn type 1" and "Tawn type 2". The following table shows the ...
