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?
a- plot all data together on a dot plot to assess if there is any visible correlation between the data sets.
b- offer a conclusion based on the data you observed.
c- pick two points on the dot plot and find a line of best fit.
d- find the correlation coefficient to see how well the line of best fit actually fits the data.
