Sample of Pipe-Apples
- Random sample of 500 pipe-apples were taken from a large consignment
- 65 pipe-apples in the sample were found to be bad
Estimation of Proportion of Bad Pipe-Apples
- The proportion of bad pipe-apples in the sample is calculated as 65/500 = 0.13
- This proportion can be used to estimate the proportion of bad pipe-apples in the entire consignment
- Thus, the estimated proportion of bad pipe-apples in the consignment is 0.13 or 13%
Standard Error of the Estimate
- The standard error of the estimate is a measure of the variability of the sample estimate
- It is calculated as the square root of (sample proportion x (1 - sample proportion) / sample size)
- For this sample, the standard error of the estimate is sqrt(0.13 x (1 - 0.13) / 500) = 0.022
Confidence Interval
- A confidence interval is a range of values within which the true population parameter is expected to lie
- The confidence interval is calculated as the sample estimate plus or minus a margin of error
- The margin of error is calculated as the product of the standard error of the estimate and the appropriate critical value based on the desired level of confidence
- Assuming a 95% confidence level, the critical value is 1.96
- Thus, the margin of error is 1.96 x 0.022 = 0.043
- The confidence interval for the proportion of bad pipe-apples in the consignment is therefore 0.13 +/- 0.043, or 0.087 to 0.173
- This means that we can be 95% confident that the true proportion of bad pipe-apples in the consignment lies between 8.7% and 17.3%
