In order to determine the margin of error you need to decide a confidence level, 95% is one of the most popular confidence levels to use.Answer and Explanation: In order to find the sample size of a data set for
The sample size is a statistic that is used in the calculation of confidence interval. The sample size for proportion is calculated by the given formula: Sample size=(Zα/2)2×p(1−p)ε2where ε is margin of error The sample size is denoted by n...
Our margin of error (from the question), is 0.5. 7.482/0.5 = 14.96 Step 4: Square Step 3. 14.96 * 14.96 = 223.8016 Back to top Find a sample size to estimate a population mean Watch the video to find out how to find a sample size if you want to estimate means: Can’t see the...
A low value of the margin of error shows that the results obtained have higher accuracy levels for the confidence interval and vice-versa. In order to keep the margin of error on the lower side, the sample size n can be increased based on the requirement.Answer and...

i can only guess that the names of your tables are different. In my file and in the code (posted above) the names of the tables are "Tabelle1" und "Tabelle2". Perhaps you can attach your file without sensitive data. This would be very helpful to find the reason for the error ...
A random sample of size 8 from N(mu, 70) yielded xbar = 86. Find the following confidence intervals for mu: a. 99% b. 95% c. 90% d. 80% Use the given confidence interval to find the margin of error and the sample proportion. (0.608, 0.638). ...
