Hypothesis testing
Not what you're looking for?
The following hypothesis are given:
Ho: p less or equal to 0
H1: p >0
A random sample of 12 observations indicated a correlation of .32 Can we conclude that the correlation in the population is greater than 0? Use the .05 significance level.
Ho is rejected if t> 1.714
t= .32SQRT 32-5/SQRT 1-(.32)^=?
I don't know what to do beyond this.
