Output variable stat.t stat.PVal stat.df stat.x stat.sx stat.n Description (x N m0) / (stdev / sqrt(n)) Smallest level of significance at which the null hypothesis can be rejected Degrees of freedom Sample mean of the data sequence in List Sample standard deviation of the data sequence Size of the sample tTest_2Samp tTest_2Samp List1,List2[,Freq1[,Freq2[,Hypoth[,Pooled]]]] (Data list input) tTest_2Samp v1,sx1,n1,v2,sx2,n2[,Hypoth[,Pooled]] (Summary stats input) Computes a two-sample t test. A summary of results is stored in the stat.results variable. (See page 97.) Test H0: m1 = m2, against one of the following: For Ha: m1< m2, set Hypoth m2, set Hypoth>0 Pooled=1 pools variances Pooled=0 does not pool variances For information on the effect of empty elements in a list, see "Empty (void) elements" on page 131. Output variable stat.t stat.PVal stat.df stat.x1, stat.x2 stat.sx1, stat.sx2 stat.n1, stat.n2 stat.sp Description Standard normal value computed for the difference of means Smallest level of significance at which the null hypothesis can be rejected Degrees of freedom for the t-statistic Sample means of the data sequences in List 1 and List 2 Sample standard deviations of the data sequences in List 1 and List 2 Size of the samples The pooled standard deviation. Calculated when Pooled=1. tvmFV() tvmFV(N,I,PV,Pmt,[PpY],[CpY],[PmtAt]) ⇒ value Financial function that calculates the future value of money. Note: Arguments used in the TVM functions are described in the table of TVM arguments, page 107. See also amortTbl(), page 6. 106 TI-Nspire™ Reference Guide Catalog > Catalog >
