Question

The data in the attached image represents blood pressure based on a new trial medication used in an experiment involving a total of 50 male and female subjects.  There were two levels of treatment: 0 = placebo and 1 = treatment group. Family History Blood Pressure = Fam-Hist-BP; from the paternal side = PS; from the maternal side = MS; from both sides = BS; none on both sides or not known = N.; Blood pressure before the experiment = BP-Before-Exp; Blood pressure after the experiment = BP-After-Exp.

Task: Find the mean and standard deviation for the family history group, the before treatment group, and the after treatment group.
