4. My Notes -/8 points Researchers are interested in testing against the null hypothesis that there is no correlation between female life expectancy and infant death rates. They collect data on n-97 countries and calculate a 95% CI for P of (-0.9700,-0.9338). (You have one attempt for each of the problems below.) 1. How should the null hypothesis be written? Ho: r = 0 Ho: #1 #₂ = 0 Ho: μ = 0 Ho: P = 0 2. The result of the hypothesis test is: We do not have evidence that there is a significant correlation, because the null value is outside the 95% CI. We do not have evidence that there is a significant correlation, because the null value is inside the 95% CI. We have evidence that there is a significant correlation, because the null value is inside the 95% CI. We have evidence that there is a significant correlation, because the null value is outside the 95% CI 4.
