• No Correlation

• Lots of Correlation

• Positive Correlation

Pat owns a bakery and wants to determine whether there is a relationship between the temperature outside and hot cocoa sales at the bakery. The data table below shows the temperature over 10 randomly selected days last year and the gross sales from hot cocoa on those days. What is the correlation coefficient between temperature and hot cocoa sales at Pat's bakery, and what does the coefficient indicate? Reminder: desmos cheater method (what is r?) The correlation is ​ (a)   and indicates there is​ ​ (b)   association.

• -0.93

• a strong negative linear

• -0.95

• little to no linear
