12. a professor obtains sat scores and freshman grade point averages (gpas) for a group of n = 15 college students. the sat scores have a mean of m = 580 with ss = 22,400, and the gpas have a mean of 3.10 with ss = 1.26, and sp = 84. a. find the regression equation for predicting gpa from sat scores. b. what percentage of the variance in gpas is accounted for by the regression equation? (compute the correlation, r, then find r2.) c. does the regression equation account for a significant portion of the variance in gpa? use α = .05 to evaluate the f-ratio. gravetter, frederick j. statistics for the behavioral sciences (p. 556). cengage learning. kindle edition.

Brainliest! 1. you suspect that the spiciness of food served in a restaurant is positively correlated with number of soft drinks ordered. 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. observe several cases of people ordering food of varying spice-levels and number of soft drinks ordered. pick two points on the dot plot and find a line of best fit. find the correlation coefficient to see how well the line of best fit actually fits the data. 2. given the data set for the height and shoe size of every student in a math class, hypothesize a relationship between the variables. i would expect the data to be positively correlated. i would expect the data to be negatively correlated. i would expect no correlation. there is not enough information to determine correlation.
