To find the P-value for a lower-tail z-test, we need to look up the z-score in the standard normal distribution table (z-table).

Step 1: Look up the z-score in the z-table.
The z-table gives us the probability that a standard normal random variable is less than or equal to a given value. In this case, our z-score is 0.09.

Step 2: Find the corresponding probability in the z-table.
Looking up 0.09 in the z-table, we find a probability of 0.5359. This means that approximately 53.59% of the data falls below a z-score of 0.09.

Step 3: Calculate the P-value.
Since this is a lower-tail test, the P-value is the probability that we found in the z-table. Therefore, the P-value for this z-test is 0.5359.
