amistre64 · Answer

then we are stuck between z=1 and z=2

amistre64 · Answer

how accurate of an answer do we need?  is this related to the empirical rule or the ztables?

amistre64 · Answer

by the empirical rule:

we have 95/2 % of the data between the mean and z=2

we have 68/2 % of the data between the mean and z=1

therefore, we have z2 data - z1 data between them
