WebFor the 2-sample t-test, the numerator is again the signal, which is the difference between the means of the two samples. For example, if the mean of group 1 is 10, and the mean of group 2 is 4, the difference is 6. The default null hypothesis for a 2-sample t-test is that the two groups are equal.
WebApr 17, 2024 · Günter Blobel won a Nobel Prize for his “signaling hypothesis” explaining how signal peptides target secretory proteins to a translocase channel embedded in the membrane of the endoplasmic reticulum ( 2 ).
