Final answer:
To calculate the area under the standard normal distribution curve between z=-0.55 and z=-1.20, you must find the respective areas to the left for both z-scores from a z-table and subtract them.
Step-by-step explanation:
To find the area under the standard normal distribution curve between z=-0.55 and z=-1.20, you must use a z-table. This table provides the area to the left of a given z-score for a standard normal distribution. First, look up the area to the left of z=-0.55, then find the area to the left of z=-1.20, and subtract the smaller area from the larger area to get the area between the two z-scores.
Unfortunately, without the exact values from the z-table, we cannot provide the precise area. However, generally speaking, your answer would be in the format:
- Area to the left of z=-0.55: (find this value in the z-table)
- Area to the left of z=-1.20: (find this value in the z-table)
- Area between z=-0.55 and z=-1.20: (subtract the two areas)
Remember, most z-tables show the area to the left of z, so you might need to subtract the table value from 1 if you're looking for the area to the right.
