Question 3
What is the area under the normal curve between the z-scores of −1 and 0?
To find the area under the normal curve between two z-scores, you will need to use a standard normal distribution table or a calculator with a normal distribution function.
1. Standardize the z-scores: In this case, the z-scores are -1 and 0, which means they represent the number of standard deviations from the mean.
2. Locate the area corresponding to the first z-score: Look up the area to the left of -1 in the standard normal distribution table. This area represents the proportion of the distribution below -1.
3. Locate the area corresponding to the second z-score: Look up the area to the left of 0 in the standard normal distribution table. This area represents the proportion of the distribution below 0.
4. Calculate the area between the two z-scores: Subtract the area for the first z-score from the area for the second z-score. This will give you the area under the normal curve between the two z-scores.
Note: If you are using a calculator, you can use the normal distribution function to directly find the area between the two z-scores by inputting the z-scores and specifying the range.
Now you have the steps to find the area under the normal curve between the z-scores of -1 and 0. You can apply those steps using a standard normal distribution table or a calculator with a normal distribution function to find the exact value.
