x = c(1,2,3,4,5,6,7,8,9,10)
y = c(7,8,9,10,11,12,13,14,15,16,17,18,19,20)
t.test(x, y) # P = .00001855

x = c(1,2,3,4,5,6,7,8,9,10)
y = c(7,8,9,10,11,12,13,14,15,16,17,18,19,20,200)
t.test(x,y) # P = .1245

A1 = c(30.02, 29.99, 30.11, 29.97, 30.01, 29.99)
A2 = c(29.89, 29.93, 29.72, 29.98, 30.02, 29.98)
t.test(A1, A2)

A = c(12,16,19,8,10,13,6,15,14)
B = c(15,5,11,8,9,9,5,11,10)
t.test(A,B)

→ t=1.9528, p=0.06978
