Hi everyone,
I am trying to calculate the independent t-test using ttesti which requires mean, sd, and sample size. Given that I do not have sd but semean, I need to convert the semean to sd using semean*(10^1.5) formula. My question is how can I specify the multiplication noted above within the ttesti command. I have tried the below code but I got an error: "'31.41644 0.181502' found where number expected". Obviously, one non-efficient solution could be using the display command to obtain the result for the multiplication, but I wonder if there is any way to do the job within the ttesti command itself.
Thanks,
NM

Code:
ttesti 1000 31.41644 0.181502*(10^1.5) 1000 28.6431 0.3995219*(10^1.5)
