I had a question around the wording of a problem, as I wrap my head around it...
t-distribution problem, and the wording of "significantly" specifically.
I've stated the Hypothesis, however in calculating my t, I get 5.617 and when comparing it to the tables, it's quite large. Must be something simple I'm missing.
The hypothesis used is to test whether the mean for the population is "significantly" greater than the sample. Where the sample mean is 637 and the population mean is 520. Std Dev is 148 in a sample of 50
Maybe it's the wording, but can someone help me wrap my head around this?
You can probably assume that they mean "statistically significant" in the context a t-test
question like this.
Though "statistically significant" is usually relative to the question at hand, historically this would imply a level of significance equal to 5% or 1%, i.e. with 95% or 99% confidence.
