The correlation between income and water use was analyzed at the census block groups level for a study area. The Pearson's correlation coefficient was 0.36 (r=0.36) with p<0.01. The normality of income was also checked with Kolmogorov-Smirnov test and the test result is significant at p<0.05. Which of the following statements is TRUE:
- There is a significant linear relationship between water use and income because r<0.5.
- The normality test shows that income follows a normal distribution.
- The significant result of the normality test suggests that the significance test on the Pearson's correlation coefficient is not trustworthy.
- If the data are aggregated to the census tract level, the correlation coefficient between income and water use will still be 0.36.
