2. Beach resorts had annual reports on numbers of drowning accidents, ice cream sales, and numbers of visitors. Assume that the numbers of drowning accidents, ice cream sales, and visitors were all normally distributed. The Pearson’s correlation between drowning accidents and ice cream sales was .678, the Pearson correlation between drowning accidents and number of visitors was .895, and the Pearson correlation between ice cream sales and number of visitors was .743. What was the correlation between drowning accidents and ice cream sales while keeping number of visitors constant?
