Use Excel to look up the following Z values. Note thatZ_A is the Z-value that gives you the associatedprobability or the area under the curve (A – Area). Write out theExcel function and inputs used for your calculation.

a. P(Z.70)= .70 Show solution graphically. Makesure the probability and z value are clearly labeled.

b. P(Z>Z_.12)= .12 Show solution graphically. Makesure the probability and z value are clearly labeled.

c. P(-Z_AA)= .88 Assume thatprobability is centered in the middle of the distribution. Showsolution graphically. Make sure the probability and z value areclearly labeled.
