**MathGuru**, Tuesday, February 25, 2014 at 6:48pmI'll get you started.

Hypotheses:

Ho: µ = 12 --> this is the null hypothesis

Ha: µ ≠ 12 ---> this is the alternate or alternative hypothesis

Note:

Null hypothesis always uses an equals sign. The alternate or alternative hypothesis in this case uses a "does not equal" sign because the problem is just asking if there is a difference. There is no specific direction mentioned (such as "greater than" or "less than" or similar statements).

I'll let you take it from here.
