Use the normal distribution table
https://www.math.arizona.edu/~rsims/ma464/standardnormaltable.pdf
From the Table, find the input entries that provide the closest values
to value (1-0.44) = 0.56 in the Table.
There are 2 (two, TWO) such entries : one positive and one negative.
Of these two entries, you need the highest of them, i.e. POSITIVE entry.

That's all.
So simple . . .
