Sample Size for Population Proportion Problems

Move the slider to select a new problem. Check the box to see the answer.

There will be a problem like this on Test 4 and possibly the final exam. Note that the results from the formulas are rounded up to the next integer if there is any non-zero digit to the right of the decimal point. This applet was developed from problems 31 through 36 on pages 340-41 of Mario F. Triola, "Elementary Statistics", 12th edition, Pearson Education, Inc. 2014. This applet was updated Sept. 27, 2013.
