Understand that the problem is asking for the area to the right of a z-score of -0.44 on the standard normal distribution curve.
Recall that the standard normal distribution is symmetric around a mean of 0 with a standard deviation of 1.
Use a standard normal distribution table (z-table) or a calculator to find the cumulative probability for a z-score of -0.44. This gives the area to the left of the z-score.
Subtract the cumulative probability found in the previous step from 1 to find the area to the right of the z-score, as the total area under the curve is 1.
Verify the result by checking the options provided and ensuring the calculated area matches one of the given choices.
