maxX z7(STAT)2(VAR)cc2

Determines the maximum value of the samples.

P( z7(STAT)3(DISTR)1

For the argument t, determines the probability of standard normal distribution P(t).

P (t)

P(t) =	1	∫−∞t e−	x2

R( z7(STAT)3(DISTR)3

For the argument t, determines the probability of standard normal distribution R(t).

R (t)

R(t) =	1	∫	+∞	−	x2

0t

't z7(STAT)3(DISTR)4

Using the value (X) input immediately before the command as the argument, uses the following formula to determine standardized variate t.

X't = X – o
