How to fill out 2 confidence intervals with

1. Step 1: Determine the level of confidence you want for your confidence intervals. This is usually expressed as a percentage, such as 95% or 99%.
2. Step 2: Collect the data that you will use to calculate the confidence intervals. Make sure to have a sample size that is large enough to meet the assumptions of the method being used.
3. Step 3: Calculate the sample mean and sample standard deviation. These will be used in the formula to calculate the confidence intervals.
4. Step 4: Choose the appropriate confidence interval formula based on the distribution of your data and the assumptions of the method being used. Common formulas include the t-distribution formula for small sample sizes and the z-distribution formula for large sample sizes.
5. Step 5: Substitute the values from step 3 and the level of confidence from step 1 into the chosen formula. Calculate the lower and upper bounds of the confidence intervals.
6. Step 6: Interpret the results. The confidence intervals provide a range of values within which the population parameter is likely to fall. The wider the interval, the less precise the estimate.
7. Step 7: Repeat steps 2-6 if you need to calculate a second confidence interval for a different population or parameter.
8. Step 8: Document your findings and methodology. Include the level of confidence, sample size, sample mean, sample standard deviation, and the calculated confidence intervals.
