An airline promotion to business travelers is based on the assumption that no more than two-thirds of business travelers use a laptop computer on overnight business trips.

1. What is the sample proportion from an American Express-sponsored survey that found 365 of 543 business travelers use a laptop computer on overnight business trips (to 2 decimals)?

2. What is the p-value (to 4 decimals)?

To find the sample proportion from the given information, you need to divide the number of business travelers who use a laptop computer on overnight business trips by the total number of business travelers surveyed.

1. Sample Proportion:
The number of business travelers who use a laptop computer on overnight business trips is given as 365 out of 543. Divide 365 by 543:

Sample Proportion = 365/543 ≈ 0.6721 (to 2 decimal places)

Therefore, the sample proportion is approximately 0.6721.

To find the p-value, you would need additional information such as the population proportion or a null hypothesis assuming a specific population proportion. Without that information, it is not possible to determine the p-value.
