The formula to calculate the t-statistic for a one-sample T-test is shown below. Where: x̄ –The sample mean μ –The hypothesized mean; in this case, the population mean sx̄ –The SEM So, to work this out in Excel, click on an empty cell and enter the following… =(x̄...

you have used NORM.DIST as an alternative testing method for t-test, even though it may not be as desirable. As the t statistic has the form of normalized value, it seems that the choice of the standardized normal NORM.S.DIST is more intuitive one for p-value and critical value calcula...
We see thatn1 = 17 and runs = 10. Sincen1 ≤ 20, we need to use the runs table inRuns Test Table. Consulting the runs table we see that runs in the interval [8, 19] are acceptable. Sincer= number of runs = 10 is in this interval, we cannot reject the null hypothesis at the ...
This is because one of my samples is 17, but the other one is close to 3000, also I would like to be able to calculate values for a larger significance (I would rather to actually calculate the p value corresponding to the statistic that I got). ...
1. Calculate the required sample size by defining Z-score (95%, 1-96), error (example 0, 03), and p (say .5 for maximum sample size) then estimate the sample statistic (example sample proportion). Then we say the calculated sample proportion is an unbiased estimator of the population ...
toolt-Test: Two-Sample Assuming Equal Variances. The test statistic (T Stat in the Excel output) and the Critical t value (t Critical two-tail in the Excel output) will have the same sign (as they always should) only if the sample group with the larger mean is designated the first ...

The Wilcoxon Signed-Rank test is a nonparametric equivalent of the One sample t-test. Run it in Excel using the XLSTAT statistical software.
All I was trying to do with those graphs is to gather some statistic. Product specifications (= tolerances from requirements of customer point of view) and type of article are all deterimated on the drawings. Defective products for sure always in my excel tables exsist. You can see them (...
