H0: Participants have a negative attitude towards topic X (m<3).

Ha: Participants do not have a negative attitude towards topic X (m>=3).

What I THINK I want is a one sample t-test. However, my hypothesized mean is that the "mean will be less than 3", and not "m=3"...so I'm not sure how I would use the t-test without a single expected mean. I feel like there's a different statistic I'm missing.

Looking for a nudge in the right direction!

Much appreciated,

Lee
