A correlation coefficient of .35 indicates a moderate positive relationship between level of hopelessness and suicide. The fact that there is a less than 5 in 100 probability that this correlation was found by chance alone suggests that it is statistically significant. This means that the correlation is unlikely to be a result of random chance, and is likely to reflect a true relationship between the variables.
