## Computation of 95% confidence interval

 My 10 variables are var1, var2, ...var10. I have N=500 in the file.  Appreciate if someone can provide SPSS syntax that will generate the mean and the 95% CI of the mean. The outputs should look like as follows:Variables          Mean      95%LowerLimit      95%UpperLimitVar1                 4.60         2.16                       4.90Var2                 3.88         1.32                       4.00Var3                 4.00         2.00                       4.89...Var10               3.99        3.00                         4.99Thank you for your help.Lema ===================== To manage your subscription to SPSSX-L, send a message to [hidden email] (not to SPSSX-L), with no body text except the command.
