Please choose one answer. Findings are statistically significant if: 0 Both lower and upper limits ofa 95%Cl for Relative Risk are greater than 'I. 0 Upper limit but not the lower limit ofa 95%CI for Relative Risk is a negative number. 0 Lower limit but not the upper limit ofa 95%CI for Relative Risk is less than 1. 0 Lower limit but not the upper limit of a 95%CI for Relative Risk is a negative number. If Pearson's correlation coefficient 'r value' is 0.75 what will be the value for the measure of association and effect based on this r value? (these measures associate' an exposure with a particular outcome & also indicate the 'effect' or practical significance of this exposure-outcome association, hence suitably called measures of effect and association'). Please calculate and type in your final answer as percentage with two decimals after correct rounding. Percentage symbol % with your answer is not required
