A student is assessing the correlation between the number of workers in a factory and the number of units of output produced daily. The table below shows the data:
Number of workers
(x) 0 10 20 30 40 50 60 70 80 90
Number of units of output
(y) 2 52 102 152 202 252 302 352 402 452
Part A: Is there any correlation between the number of workers in a factory and the number of units of output produced daily? Justify your answer. (4 points)
Part B: Write a function which best fits the data. (3 points)
Part C: What does the slope and yintercept of the plot indicate? (3 points)

Best ResponseYou've already chosen the best response.1That is correct. But I meant are both sets of numbers increasing x's and y's? Is one row increasing while the other is decreasing? Are both rows decreasing? Are both rows growing?
