The significance of the slope of the regression line is determined from the t-statistic. It is the probability that the observed correlation coefficient occurred by chance if the true correlation is zero. Some researchers prefer to report the F-ratio instead of the t-statistic. The F-ratio is equal to the t-statistic …

The statistic t has the same interpretation as any standardized statistic: it says how far is from its mean μ in standard deviation units. There is a different t distribution for each sample size. We specify a particular t distribution by giving its degrees of freedom (df).
