Question

Express the confidence interval 0.254 + 0.048 in the form of p-E

Answer 1

The confidence interval expressed in the form of p-E is (0.206, 0.302). It estimates the true population proportion with a certain level of confidence.

Step-by-step explanation:

The confidence interval expressed as p-E is (0.254 - 0.048, 0.254 + 0.048) = (0.206, 0.302).

This means that we estimate with a certain level of confidence that the true value of the population proportion is between 20.6% and 30.2%.

This confidence interval was likely calculated using a formula or statistical method based on sample data.

Answer 2

The confidence interval 0.254 + 0.048 can be expressed in the form of p-E as (0.206, 0.302).

Step-by-step explanation:

A confidence interval is a statistical range that expresses the uncertainty around a sample estimate. It provides a range of values within which the true population parameter is likely to fall, along with a specified level of confidence. A common confidence level is 95%, indicating a 95% likelihood that the true value lies within the interval.

The confidence interval 0.254 + 0.048 can be expressed in the form of p-E. In this case, p is the estimated proportion and E is the error bound. So, the confidence interval is (0.254 - 0.048, 0.254 + 0.048), which simplifies to (0.206, 0.302).
