Imagine you do an anova and plot the means. on the y-axis is the group mean, on the x-axis different levels of one factor. different levels of another factor are plotted as separate lines. what would you expect these lines to look like if there were only an interaction effect, but no main effects?

City l has a temperature of −3 °f. city m has a temperature of −7 °f. use the number line shown to answer the questions: number line from negative 8 to positive 8 in increments of 1 is shown. part a: write an inequality to compare the temperatures of the two cities. (3 points) part b: explain what the inequality means in relation to the positions of these numbers on the number line. (4 points) part c: use the number line to explain which city is warmer. (3 points)
