Dear Nick and Maarten, Thank you for reply. Form p-value, z=1.7 is not significant. But when I check z-table, value 1.7 meets with area between mean and 1.7 equals 0.4554. Looks like it is at 10% significance level. But why p-value shows it is insignificant? I think there must be something wrong when I interpret the result from z-table. But I can not figure it out. Can you help me with this? Thank you.
