Suggest how you would design and conduct this experiment.

**MathGuru**, Tuesday, April 16, 2013 at 8:47pmUsing a formula for a binomial proportion one-sample z-test with your data included, we have:

z = .62 - .50 / √[(.50)(.50)/50]

Finish the calculation.

Use a z-table to find the critical or cutoff value at 0.01 for a one-tailed test.

If the z-test statistic calculated above exceeds the critical value from the z-table, reject the null. If the z-test statistic does not exceed the critical value from the z-table, do not reject the null.

I hope this will help get you started.
