The total area under the normal curve is equal to 1.0. Since, the normal curve is symmetric about the mean value. The normal area tables, helps us to find the probability value for the left of z score. Area Left to z score can be written symbolically P( z < a) Area right to z score can be written symbolically P(z > a) While, P( z > a) = 1 - P(z<a) The total area under the standard normal curve to the left of z =-2 or to the right of z = 2 is P( z < -2) + P(z > 2) = P(z <-2) + [ 1 - P( z < 2) ] = 0.02275 + [ 1 - 0.97725] [ Use the below table values] = 0.02275 + 0.02275 = 0.0455 Therefore, the total area under the standard normal curve to the left of z =-2 or to the right of z = 2 is 0.0455 Area values when left of the z score is negative : From the above table, The P- value is 0.02275 at the z score of -2.0 Area values when left of the z score is positive : From the above table, The P- value is 0.97725 at the z score of 2.0 The total area under the standard normal curve to the left of z =-2.52 or to the right of z = 1.52 is P( z < -2.52) + P(z > 1.52) = P(z <-2.52) + [ 1 - P( z < 1.52) ] = 0.00587 + [ 1 - 0.93574] [ Use the below table values] = 0.00587 + 0.06426 = 0.0701 Therefore, the total area under the standard normal curve to the left of z =-2.52 or to the right of z = 1.52 is 0.0701 Area values when left of the z score is negative : From the above table, The P- value is 0.00587 at the z score of -2.52 Area values when left of the z score is Positive : From the above table, The P- value is 0.93574 at the z score of 1.52 The total area under the standard normal curve to the left of z =-0.61 or to the right of z = 1.18 is P( z < -0.61) + P(z > 1.18) = P(z <-0.61) + [ 1 - P( z < 1.18) ] = 0.27093 + [ 1 - 0.8810] [ Use the below table values] = 0.27093 + 0.1190 = 0.3899 Therefore, the total area under the standard normal curve to the left of z =-0.61 or to the right of z = 1.18 is 0.3899 Area values when left of the z score is negative : From the above table, The P- value is 0.27093 at the z score of -0.61 Area values when left of the z score is positive : From the above table, The P- value is 0.88100 at the z score of 1.18
