Use the standard normal distribution table to determine the percent of data between z=0.15 and z= 1.23. Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table. The percent of data between z= 0.15 and z= 1.23 is (Round to two decimal places as needed.) %

Answer 1

The percentage of data between 2-0.15 and 2-1.23 is: P(0.15<2C 1.23)=P(Z <1:23)-P(Z <0.15) f(2) area between 2-0.15 82=1.23 - Z 0.15 1.23 +2 Plo.is <2<1, 23) = 0.89065 0.55962 (from standard normal table values) P(0.is < 221.23) = 0. 33103 The percentage of data between 2-0.15 f Z= ), 23 is 33.103 %

The table values are taken from standard normal table which represents the AREA to the LEFT of the Z score.

The percentage of data between z=0.15 & z=1.23 is 33.10%.
