The area between -1.75 and 1.75 is equal to .91988 or .92

I would use those z-values.
You can get these values from looking at a z-table. There are many different version of z-tables. You might be able to see the tails in it or a cumulative area z-table. Think of 92% being in the middle leaving 4% in each tail or .04,
