A scientist is studying the relationship between the depth of a watermelon vines' roots and the weight of the watermelons produced. The scientist collects measurements from a random sample of vines. He then conducts a significance test in which the null hypothesis is that there is no correlation between the two variables (correlation = 0) versus the alternative that the correlation is greater than 0. From this test he found a
P-value of 0.0032. What does this tell us?
A) There is significant evidence that the correlation is greater than 0 at the 0.05 level.
B) There is no significant evidence that the correlation is greater than 0 at the 0.05 level.
C) The correlation is very small.
