Question 1126853: Please help me with hypothesis testing questions in statistics,
State the null and alternative hypotheses for the situation described below for a statistical test. Your answer should be an expression composed of symbols:
Testing to see if there is evidence that a correlation between height and salary is significant (that is, different than zero.)
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! Ho: p=0, the correlation is 0
Ha: p NE 0, the correlation is not 0.
If the null hypothesis is rejected, then the conclusion will be that the correlation is not zero.
There will be a test statistic that will almost certainly not be zero, but the error involved in calculating the test statistic can allow one to calculate the probability that such a value could occur given the null hypothesis. If such a value is highly unlikely (a small p-value) then the null hypothesis might be rejected (depending upon what the critical value was determined beforehand).
