You complete a rigorous scientific study of salinity levels and its affect on the speed of a species of fish inhabiting brackish water.You plot salinity level on the x axis and fish speed on the y axis and see that as salinity increases so does fish speed.Much of your data fall very close to the trend line and your p-value is 0.01 after carrying out a statistical test.This would mean that:
A) There is an association between salinity level and fish speed B) There is a lot of variation in the effect of salinity upon fish speed C) The data will be more than two standard deviations away from the mean D) Enough data have been collected to conclude with confidence that there is a relationship between salinity and fish speed
