To find the 90% confidence interval for the population standard deviation, you randomly sample with replacement from the original sample thousands of times. From each new sample, you compute the sample standard deviation. Using the bootstrap method, how can you find the 90% confidence interval for the population standard deviation from these values?

use 5th and the 95th percentile of these values.

Step-by-step explanation:

To find the 90% confidence interval for the population standard deviation, randomly sample with replacement from the original sample thousands of times. From each new sample, you compute the sample standard deviation. Using the bootstrap method, we can find the 90% confidence interval for the population standard deviation, from the values of 5th and the 95th percentile of these values.

So we need to use 5th and the 95th percentile of these values.
