**MathGuru**, Tuesday, June 18, 2013 at 5:04pmUse z-scores and a z-table for this problem. Because you are given a sample size, you will need to include the sample size in the calculation:

z = (x - mean)/(sd/√n)

Your data:

z = (11.29 - 11.5)/(2.7/√36)

Finish the calculation. Use the z-table to find the probability (remember that the problem is asking "less than 11.29" when looking at the table).

I hope this will help get you started.
