st: critical value

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.
Best Regards,
Lynn Lee

Alongside the column reporting the z statistics is a column headed "P
> |z|" which gives this information.
