Chapter 8.2, Problem 2.2CYU

To determine

To check: The condition to construct the confidence interval for the parameter.

Explanation of Solution

Given:

Number of students ( n ) = 10904

Number of binger drivers ( x ) = 2486

Confidence level = 99%

Concept used:

Following are the main conditions for the confidence interval of population proportion:

1. Data must be random.
2. Values must be independent of each other.
3. Number of success and failures should be more than or equal to 10
4. Sample size must be no more than the 10% of the population.

Following conditions are satisfied here:

1. Students were randomly chosen.
2. Number of failures and successes are at least 10.
3. Students have been randomly chosen.
