Answer:
36.69%
Step-by-step explanation:
Given a standard normal distribution :
P(Z < - 0.34) :
Using the Z distribution table :
Look up the value - 0.3 down the row and 0.04 a cross the column. The value at the intersection of the two points gives the required proportion:
P(Z < - 0.34) = 0.3669
0.3669 as a percentage = 0.3669 * 100% = 36.69%
The value can also be obtained using the Z probability calculator.
