You suspect that the spiciness of food served in a restaurant is positively correlated with number of soft drinks ordered. You have gathered several observations of people ordering food of different spice-levels and the number of soft drinks they ordered. You have also plotted the data and found a line of best fit. What would be your next steps to test your hypothesis?

Plot all data together on a dot plot to assess if there is any visible correlation between the data sets.

Offer a conclusion based on the data you observed.
