Statistics: Difference between results from doing a confidence interval and from doing a t-test?
Even if we get the same results, why might our results with the confidence interval differ from those of the t-test?
I think it has something to do with alpha (which for this is .05).

ANSWER: A Confidence Interval describes the probability that a sample mean will be equal to a value within the Interval. A 95% Confidence Interval is 95% probability that a sample mean will have a value within the Interval. If 95% Confidence Interval = [1, 5] then a sample mean that a Statistician measures will have 95% probability of a value within the Interval [1, 5].
A t-test is the probability that the sample mean matches up to the Table of values. A t-test for a sample size 5 (4 degrees of freedom) has a computed "Standard Value" of 2.1 which has the "look-up" Table a probability of 5.1% (0.051) is larger than alpha = 0.05. The t-test shows the sample mean matches up to the Table of values.

...while you're a this kind of mat-E you will desire to probably understand an amino acid is actual a very basic chemical shape. It does not ask your self me in case you are able to desire to discover them created someplace interior the universe different than earth. & Darwin grow to be reported in a time the place that grow to be the norm. you are able to desire to appreciate which you think what you're reported around (for the main area). interior the early days or rocketry, no person would desire to hold close the elementary concepts or thrust and stability. you are able to now pass and throw one mutually out of cardboard and plastic and it exceeds previous expectancies ten fold. Its time-era relative. considered one of my issues of the argument for clever layout is that every time the theory is provided with a issue that their cutting-edge good judgment can not forget (say.. evolution, which grow to be not common for an quite long term), they then annex that and declare they have been suited the excellent time. moving on, while you're speaking approximately D and L systems.. one is extensively common because of the fact the vivo and the different because of the fact the vitro kind. that's authentic for many organic and organic molecules. i'm not asserting i understand all the solutions yet my individual take is evidence has been consistently surfacing for the final couple hundred years which each and every time advances what we "understand" approximately life. Why then verify which you will desire to make some very final opinion now? what you "understand" now's thoroughly beside the point to what human beings "understand" in a 300 and sixty 5 days or 2. as a substitute of struggling with for some worldwide reason claiming that one view is right why not extra check out to discover extra suggestion and evidence to the two area of the 'tale'? I propose, why does preaching to a random individual supply extra delight than assisting the popular reason for gaining know-how of how life applications or the place it got here from. extra evidence = a clearer answer.
