Answer:
(b) 12, 19, 15
(d) 14, 20, 12, 19, 15
(e) 12, 13, 13, 12, 43, 15, 19
Step-by-step explanation:
We are given the following information in the question:
12, 19, 13, 43, 15
The above is a sample of taxi-out times (in minutes).
We have to find possible bootstrap samples.
Bootstrap Sample:
- A bootstrap sample is taken from the given sample obtained by drawing from the given sample with replacement,.
- Also, the bootstrap sample will always have the same data points as the original sample.
(a) 12, 19, 13, 43, 15
This is a bootstrap sample as it contains five data points and all belong to the original sample.
(b) 12, 19, 15
This cannot be a bootstrap sample as it contains less number of data points as compared to the original sample which is 5.
(c) 12, 12, 12, 43, 43
This is a bootstrap sample s it contains five data points and all belong to the original sample.
(d) 14, 20, 12, 19, 15
This cannot be a bootstrap sample as this sample contains 14, which is not in the original sample.
(e) 12, 13, 13, 12, 43, 15, 19
This cannot be a bootstrap sample as it contains more number of data points as compared to the original sample which is 5.
