Astudent 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 y-intercept of the plot indicate? (3 points)
