The following data was collected to explore how the average number of hours a student studies per night and the student's GPA affect their ACTscore. The dependent variable is the ACT score, the first independent variable (x1) is the number of hours spent studying, and the secondindependent variable (x2) is the student's GPA.Effects on ACT ScoresStudy Hours GPA ACT Score02171220322554265426Copy DataStep 2 of 2: Determine if a statistically significant linear relationship exists between the independent and dependent variables at the 0.05 level ofsignificance. If the relationship is statistically significant, identify the multiple regression equation that best fits the data, rounding the answers tothree decimal places. Otherwise, indicate that there is not enough evidence to show that the relationship is statistically significant.Answer How to enter your answer (opens in new window) 2 PointsKeypadKeyboard ShortcutsSelecting a checkbox will replace the entered answer value(s) with the checkbox value.

Jim and Larry run a soup stand. The data below represents the sales of soup that they had on 8 randomly selected days, along with the high temperature on that day. a) Create a scatter diagram for this data set and comment on whether there is a positive or negative relationship between these variables.b) Calculate the correlation coefficient between temperature and sales.c) Does a linear relationship exist between these variables? Explain to me why or why not this is the case.d) Using excel, calculate the least squares regression equation for this data set. e) Using your equation, predict the soup sales on a day where the temperature is 29 degrees.f) Interpret the slope of this equation.g) Can we use this data set and regression equation to predict the sales on a day when the average temperature is 102 degrees? Why or why not?h) What is the R-squared for this equation? How do you interpret that R-squared?
