Use the table to make a scatter plot of the data. draw a trend line and write its equation. predict the revenue at us theme parks in 2012. (i already made the graph) 1. suppose you used a line of best fit for a set of data to make a prediction about an unknown value. the correlation coefficient for your data set is –0.025. 2. how confident can you be that your predicted value will be reasonably close to the actual value? how would you know?

I'm sorry! i really wish i could help you out more on this one. personally, i'm pretty confused myself. i think the data should have more years because i'm not sure how you're supposed to give a reasonably close predicted value when it's so far apart. your graph looks really good though other than the trend line should be straight across the points i believe. i could try to link a photo if you're not sure of what i'm talking about. i'll keep looking at this one though and let you know if i figure anything out.

Ican’t answer if there is no diagram
