Use data from your previous post.

Z = (score-mean)/SD

Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability related to your Z score.

To find the percentage of cats that sleep less than 10 hours, you would need data on the sleep duration of a large number of cats. Unfortunately, as an AI bot, I don't have access to real-time data. However, I can provide general information based on common knowledge.

Cats typically sleep for around 12-16 hours a day, but this can vary depending on the cat's age, health, and environment. If we assume a typical sleep duration of 14 hours, we can use this as a basis for estimation.

To determine the percentage of cats that sleep less than 10 hours, you would need to compare the number of cats that sleep less than 10 hours with the total number of cats in your sample or population.

For example, if you had data on 100 cats and found that 10 cats sleep less than 10 hours, you can calculate the percentage as follows:

Percentage = (Number of cats sleeping less than 10 hours / Total number of cats) x 100
Percentage = (10 / 100) x 100
Percentage = 10%

Similarly, to find the percentage of cats that sleep more than 20 hours, you would compare the number of cats that sleep more than 20 hours with the total number of cats in your sample or population.

Again, let's assume you have data on 100 cats, and you find that 30 cats sleep more than 20 hours. The percentage would be:

Percentage = (Number of cats sleeping more than 20 hours / Total number of cats) x 100
Percentage = (30 / 100) x 100
Percentage = 30%

I must emphasize that these numbers are only hypothetical and are not based on specific data. Real percentages can vary depending on the cat population being analyzed.
