Question

In a population set, 11 students out of 130 observations received a failing grade in the accounting principles course. What is the estimate of the sample proportion of failure in the course?

Answer 1

The sample proportion of failure in an accounting principles course is the number of students who failed divided by the total number of students. With 11 out of 130 students failing, the sample proportion is 0.0846 or 8.46%.

Step-by-step explanation:

The student asked about the estimate of the sample proportion of failure in an accounting principles course. To find the sample proportion, we divide the number of students who received a failing grade by the total number of observations. In this case, 11 students out of 130 received a failing grade.

To calculate the sample proportion (p-hat), use the following formula:

Sample Proportion p-hat = Number of Failures / Total Number of Observations

So, the sample proportion of failure in the course is p-hat = 11 / 130.

After carrying out the calculation:

p-hat = 0.0846

This means that approximately 8.46% of the students sampled received a failing grade in the accounting principles course.
