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
acc: the test result, 0 or 1 to reject or fail to reject the null hypothesis
tT: the test T-value
tM: the input value
prob: the lower-tail probability
df: the degrees of freedom
cT: the critical T-value associated with the input α-level
cx1: the lower critical value of the mean associated with the critical T-value
cx2: the upper critical value of the mean associated with the critical T-value
Example:
HypT1mean(0.461368, 0.2776, 50, 0.5, 0.05, 1, "")
