Variability in Activate Appointments

Hi Community!

I have setup a time schedule in the Appointments Table of "Activate Appointments" as shown:

My question is: In accordance with the 68-95-99.7 rule, what are the parameters of the normal distribution must I enter in the Variability Section in order for each of the 244 guys, to arrive early or late, within +/- 7.5mins at 68%, 15mins at 95%, and 22.5min at 99.7% of the time?

normal(???, ???, 1), where stream = 1 in this case

The normal distribution takes the mean and standard deviation as parameters, so

normal(0, 7.5, 1);

Followup Question (this might be a challenge):

Hi, what if the patient has tendencies to arrive at most 60 min early and at most 30 min late? With say, the same standard deviation of 7.5 mins? How will the formula change?

normal(0,7.5,1) ---> ???+normal(???, ???,1)
