Z zInterval zInterval s,List[,Freq[,CLevel]] (Data list input) zInterval s,v,n [,CLevel] (Summary stats input) Computes a z confidence interval. A summary of results is stored in the stat.results variable. (See page 97.) For information on the effect of empty elements in a list, see "Empty (void) elements" on page 131. Output variable Description stat.CLower, stat.CUpper Confidence interval for an unknown population mean stat.x Sample mean of the data sequence from the normal random distribution stat.ME Margin of error stat.sx Sample standard deviation stat.n Length of the data sequence with sample mean stat.s Known population standard deviation for data sequence List zInterval_1Prop zInterval_1Prop x,n [,CLevel] Computes a one-proportion z confidence interval. A summary of results is stored in the stat.results variable. (See page 97.) x is a non-negative integer. For information on the effect of empty elements in a list, see "Empty (void) elements" on page 131. Output variable Description stat.CLower, stat.CUpper Confidence interval containing confidence level probability of distribution stat.Ç The calculated proportion of successes stat.ME Margin of error stat.n Number of samples in data sequence Catalog > Catalog > 112 TI-Nspire™ Reference Guide
