**MathGuru**, Tuesday, July 30, 2013 at 7:04pmTry a one-sample z-test on this data:

z = (sample mean - population mean)/(standard deviation divided by the square root of the sample size)

z = (49 - 50)/(5/√36)

I'll let you finish the calculation.

Check a z-table for your critical or cutoff value at .05 level of significance. Compare the test statistic you calculated to the critical value from the table. Draw your conclusions.

I hope this will help get you started.
