The standard normal distribution should be in the back of your textbook, along with directions or illustrations on how to use it. You are asking for the z-value under the curve where the cumulative area is equal to 0.95.

I hear ya. Can't help, but I sympathize. Half the time, my problem is figuring out what procedure to use, and how to set something up. Good luck on this!
