A)37.4
B)72.4
C)0.00
D)68.0
E)2.0.8

We can use the formula for z-score to find the corresponding x-value:

z = (x - μ) / σ

where μ is the mean and σ is the standard deviation.

Rearranging the formula, we get:

x = z*σ + μ

Substituting the given values, we have:

x = 3.4 * 11 + 35

x = 72.4

Therefore, the answer is choice B, 72.4. This represents the time (in minutes) it would take to fill a prescription with a z-score of 3.4, assuming a mean time of 35 minutes and a standard deviation of 11 minutes.
