Find the area under the standard normal curve between z = - 1.5 and z = 2.5

Find the area between z-1.5 & z-2.5

e: Refer to your book for z score table. 1. between z = 0 and z = 2.5

To find the area under the standard normal curve between two specific z-scores, we can use a standard normal distribution table or a statistical calculator.

1. Using a standard normal distribution table:
- Look up the z-score for both -1.5 and 2.5 in the table.
- The table provides the area to the left of the z-score. So, find the area to the left of z = -1.5 and the area to the left of z = 2.5.
- Subtract the smaller area from the larger area to find the area between the two z-scores.

2. Using a statistical calculator or software:
- Use the cumulative distribution function (CDF) of a standard normal distribution to find the area between z = -1.5 and z = 2.5.
- Input the values -1.5 and 2.5 into the CDF function, with mean 0 and standard deviation 1.
- The result will be the area under the standard normal curve between z = -1.5 and z = 2.5.

Both methods will give you the area under the standard normal curve between the given z-scores.
