Researchers have collected data on the rate of BO disease from a random sample of persons across the country aged 50 and above (n = 250). In particular, researchers are curious in studying a claim made by the cig industry that there is a negative relationship between smoking cigarettes and the risk of contracting BO’s. The researchers have calculated a Pearson’s r correlation of −.709 for the two variables. The researchers have also calculated (using a computer) a significance value of .005. In a paragraph of five to six sentences, based on the results from the correlation, what conclusions can the researchers make about the relationship between smoking and getting BO’s? Ensure that you mention the unit of analysis, the direction of the relationship, the strength of the relationship, whether the findings are statistically significant, and how accurately the results would reflect the population. Do these findings support the cig industry’s claim? Why or why not?
