tM: the input Δ value
prob: the lower-tail probability
cT: the critical T-value associated with the input α-level
cx1: the lower critical value of Δ associated with the critical T-value
cx2: the upper critical value of Δ associated with the critical T-value
Example:
HypT2mean(0.461368, 0.522851, 0.2776, 0.2943,50, 50, 0, 0.05, 1, "")
ConfZ1mean
The one-sample Normal condence interval for a mean.
ConfZ1mean( ,n,s,C,[”configuration”])
Conguration: a string that controls what results are shown and the order in which they appear. An empty
string "" displays the default: all results, including headers. The options in the conguration string are
separated by spaces.
h: header cells will be created
Z: the critical Z-value
zXl: the lower bound of the condence interval
zXh: the upper bound of the condence interval
prob: the lower-tail probability
std: the standard deviation
Example:
ConfZ1mean(0.461368, 50, 0.2887, 0.95, "")
ConfZ2mean
The two-sample Normal condence interval for the dierence of two means.
