(3 points) 7. What percent of the normal curve lies between the mean and a z score of 1.512 (3 points) 8. What percent of the normal curve lies between Z-scores of -0.6 and +1.95? (3 points) 9. What percent of the normal curve lies between 2-scores of 1.24 and 2.36? (3 points)

Answer 1

The question asks about the percentage of the normal curve between specific z-scores and can be solved using the empirical rule.

Step-by-step explanation:

The question is asking for the percentage of the normal curve that lies between specific z-scores. To solve this, we can use the empirical rule, also known as the 68-95-99.7 rule, which states that approximately 68% of the values lie within one standard deviation of the mean, 95% lie within two standard deviations, and 99.7% lie within three standard deviations.

For example, to find the percentage of the normal curve between a z-score of -2 and +2, we know that 95% of the values lie within two standard deviations of the mean. Therefore, the answer is 95%.

Other questions in the prompt can be solved using similar logic and the known percentages from the empirical rule.
