For example, the rule says 95% of the normal distribution falls within 1.96-2 std. devs. of the mean, while the value i get from the z-table is around 1.65. I'm pretty sure im using the table right but i get completely wrong values. Here's how i got that value

I also did a practice test and got most of the questions involving margin of error wrong. I'm pretty sure this is because I was using the z-table to calculate the critical values.

What am I doing wrong?
