Question

Question 2: use the following sample information to calculate the confidence interval to estimate the population proportion. Let x be the number of items in the sample having the characteristic of interest. n=800 and x=489 with 95% confidence.

**Calculating Confidence Intervals for Population Proportion**

To calculate the confidence interval for estimating the population proportion, consider the following sample information. Let \( x \) represent the number of items in the sample having the characteristic of interest.

- Sample size (\( n \)) = 800
- Number of items with the characteristic of interest (\( x \)) = 489
- Confidence level = 95%

Choose the correct confidence interval from the options below:

- (0.57, 0.64)
- (0.58, 0.65)
- (0.58, 0.64)
- (0.57, 0.65)

Definition Definition Method in statistics by which an observation’s uncertainty can be quantified. The main use of interval estimating is for describing a range that is made by transforming a point estimate by determining the range of values, or interval within which the population parameter is likely to fall. This range helps in measuring its precision.
