# Statistics: Statistical Significance and Null Hypothesis

Heres the problem:

When asked to explain the meaning of "statistically significant at the 0.05 level," a student says, "This means there is only probability 0.05 that the null hypothesis is true." Is this an essentially correct explanation of statistical significance? Explain.

Can you perhaps mention some of your thoughts as to what the answer might be?

If you are finding it difficult to answer that, try to answer this: what is the definition of stat. significance?

Ahh... of course I assumed he meant his name to be pronounced with a soft j, like "halo," and all Halo aficionados are male.

No, I'm kidding, I didn't notice the name.
