The sample mean ▼ would not would be considered unusual because it has a probability that is ▼ less greater than 5%.
Use the standard normal table to find the z-score that corresponds to the given percentile. If the area is not in the table, use the entry closest to the area. If the area is halfway between two entries, use the z-score halfway between the corresponding z-scores. If convenient, use technology to find the z-score. P65
