Incorrect

The question was: What can be deduced from an 'Estimate' of 0.9461?

Your Answer: The smile means are statistically significantly higher than the neutral mean.

Answer and explanation: Your answer is incorrect. The correct answer is: The smile means are higher (on average) than the neutral mean.

The estimate is computed as:

(0.333)(Mfalse) + (0.333)(Mfelt) + (0.333)(Mmiserable) (-1.0)(Mneutral)

Since the estimate is positive, the smile sample means are, on average, higher than the neutral mean. The value of the estimate by itself does not indicate whether or not the estimate is significantly different from 0 though, for these data, it is.
