Question

Bootstrap Sample.

Here is a random sample of taxi-out times (min) for American Airlines flights leaving JFK airport: 12, 19, 13, 43, 15. For this sample, what is a bootstrap sample?

Short answer

One of the bootstrap samples for data taxi-out times (min) American Airlines flights leaving JFK airport is 43, 19, 13, 19, and 43.

Step-by-step solution

Given information

For the American Airlines flights leaving JFK airport, the sample of taxi-out times (min) is taken is given as:

12, 19, 13, 43, 15

Describe the concept of the bootstrap sample

Bootstrapping is a type of resampling method where large numbers of smaller samples of the same size are repeatedly drawn with replacement from a single original sample.

The sample size of the bootstrap sample needs to be the same as the sample size of the original data set taken with replacement.

Create a bootstrap sample

The method of bootstrapping gives a bunch of strap samples. One of them could be 43, 19, 13, 19, and 43.

This is a bootstrap sample because one has the same number of values as the original data set to this is a random sample taken from with replacement from the original data set.

Therefore, the bootstrap sample for given data is 43, 19, 13, 19, and 43.
