Finding z-scores Use Table A to fi nd the value z from a standard Normal distribution that satisfi es each of the following conditions. In each case, sketch a standard Normal curve with your value of z marked on the axis. Use an applet or your calculator to check your answers.

(a) Th e point z with 70% of the observations falling below it.

(b) Th e point z such that 90% of all observations are greater than z.

(c) Th e 46th percentile of the standard Normal distribution.
