Better than acrobat
Love it, my go to when acrobat pdf filler isn't working
The easy operation, we can count on it to fill any PDF. Acrobat sometimes let's us down so we started using this instead
The pricing, please lower it down so we can switch to this software forever. Also a nicer desktop App would be nice

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 I calculate 95% confidence interval?
To compute the 95% confidence interval, start by computing the mean and standard error: M = (2 + 3 + 5 + 6 + 9)/5 = 5. M = = 1.118. Z.95 can be found using the normal distribution calculator and specifying that the shaded area is 0.95 and indicating that you want the area to be between the cutoff points.
What does a 95% confidence interval mean?
The 95% confidence interval defines a range of values that you can be 95% certain contains the population mean. With large samples, you know that mean with much more precision than you do with a small sample, so the confidence interval is quite narrow when computed from a large sample.
How do I calculate a 95 confidence interval?
To compute the 95% confidence interval, start by computing the mean and standard error: M = (2 + 3 + 5 + 6 + 9)/5 = 5. M = = 1.118. Z.95 can be found using the normal distribution calculator and specifying that the shaded area is 0.95 and indicating that you want the area to be between the cutoff points.
What is a confidence interval in statistics?
In statistics, a confidence interval (CI) is a type of estimate computed from the statistics of the observed data. This proposes a range of plausible values for an unknown parameter (for example, the mean). The interval has an associated confidence level that the true parameter is in the proposed range.
What does 95 confidence intervals upper and lower mean?
Instead of a single estimate for the mean, a confidence interval generates a lower and upper limit for the mean. As a technical note, a 95 % confidence interval does not mean that there is a 95 % probability that the interval contains the true mean.
What does a small confidence interval mean?
Apparently a narrow confidence interval implies that there is a smaller chance of obtaining an observation within that interval, therefore, our accuracy is higher. Also, a 95% confidence interval is narrower than a 99% confidence interval which is wider. The 99% confidence interval is more accurate than the 95%.
How do you calculate confidence intervals?
Determine the confidence level and find the appropriate z*-value. Refer to the above table. Find the sample mean. For the sample size (n). Multiply z* times. And divide that by the square root of n. Take.
