Hi, I am a little bit confused with a project I am working on. This was a biology lab where we needed to find if there was more mitosis (cell division) occurring on the tip of a root or the shaft of the root.(adsbygoogle = window.adsbygoogle || []).push({});

Our class means were: 14.7% of cells on the shaft were undergoing mitosis, and 23.1% of cells on the tip were undergoing mitosis.

We calculated the standard deviation for each mean:

Tip=8.4

Shaft=7.8

And then using a t-test formula, we calculated the t value to be =4.27

We also calculated the degrees of freedom to be 66.

Now I just need help analysis the T-test. I don't really know what a value of 4.27 means. Could someone explain it? I know that I am supposed to look at a table of values, but I am still a bit lost. Any help would be appreciated!
