paired t test:
H0: difference in means of paired ca42 and ca44 is not equal to 0
p=0.0202, reject that mean of paired ca42 and ca44 is zero;
two sample t test:
H0: difference of two means of ca42 or ca44 between two treatments is 0.
p=0.1763, accept two treatments make no difference.

我想可以忽略carry-over effect and period effect.
if there is a correlation between Ca44 and Ca42, simple linear regression
model Ca44=ca42+group will make sense.

Niu! Admire.
So you have BootCode 23, Could you please share the detail steps with many of us who have same BC 23 but could not figure out the way?
Well, my CA42 cable is on the way.
Thanks!

from paired t-test, it concludes that the radioactive mean difference from
paired ca42 and ca44 is not equal to zero. but the cause lead to this
difference is ambiguous. You cannot figure out whether ca44 or vitamin-D
results in the difference. As one responder said, this experiment design can
not reach your goal.If I were you, I will choose only one radioactive Ca.
Then one group is fed with Vitamin-D and the other group without Vitamin-D.
