Use Excel to find theStandard Normal Probabilityfor the following questions. Don't forget to sketch the normal distribution and shade the required area.

a) What is the area in theleft hand tailof the standard normal curve below z = -0.73?(4dp)Answer

b) What is the area under the standard normal curvebetweenz = -2.01 and z = 2.01?(4dp)Answer

c) What is the z-value that gives theleft hand tailarea equal to 0.0384?(2dp)Answer

d) What is the absolute value of z such that thetotal areaunder the standard normal curvebetween-z and +z will be 0.9762?(2dp)
