Extremely Easy interface. Gathering Signatures is the Best and being able to do so via a text link is ingenius. Would be a 5 star if you would just offer the discounted annual purchase price.

Its great, it is exact what I was looking for. I've spent a lot of time and effort with other product/services that say they will deliver but fall short/fail actually at doing so. PDFFiller is impressive and has maintained its promised promises of delivery.

For pdfFiller’s FAQs
Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.
Identify a sample statistic. Choose the statistic (e.g, sample mean, sample proportion) that you will use to estimate a population parameter. Select a confidence level. Find the margin of error. Specify the confidence interval.
How do you document a confidence interval?
Currently, all confidence intervals calculated are two-sided confidence intervals. The formulae for the methods are provided below. N = population size n = sample size CI = confidence limit Mean = sample mean Z1-/2 = the two-sided Z value (e.g. Z=1.96 for 95% confidence interval).
How do you find the confidence limit?
To calculate the confidence limits for a measurement variable, multiply the standard error of the mean times the appropriate t-value. The t-value is determined by the probability (0.05 for a 95% confidence interval) and the degrees of freedom (n1).
How do you calculate upper and lower confidence limits?
You can find the upper and lower bounds of the confidence interval by adding and subtracting the margin of error from the mean. So, your lower bound is 180 – 1.86, or 178.14, and your upper bound is 180 + 1.86, or 181.86. You can also use this handy formula in finding the confidence interval: x ± ZA/2 * /(n).
How do you calculate lower confidence limit?
To calculate the confidence limits for a measurement variable, multiply the standard error of the mean times the appropriate t-value. The t-value is determined by the probability (0.05 for a 95% confidence interval) and the degrees of freedom (n1).
What is the upper and lower limit of confidence interval?
Standard Deviation (S) is the assumed sample standard deviation. Lower Limit is the lower limit of the confidence interval. Upper Limit is the upper limit of the confidence interval. A sample size of 40 produces a two-sided 95% confidence interval with a width equal to 15.806 when the standard deviation is 34.000.
