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.
Part B: Write a function which best fits the data.
Part C: What does the slope and yintercept of the plot indicate?

Best ResponseYou've already chosen the best response.0My Answer For Part A: Yes, The more number of workers, the more units of output. That's all I got. And I think that's wrong.

Best ResponseYou've already chosen the best response.0yes there is a correlation. If you graph it on a calculator, you will see there is a positive correlation. With the numbers in your calculator, you can run the LinReg to find the line of best fit.

Best ResponseYou've already chosen the best response.0Alright I'm making this too complicated. There's a way to use the calculator to find the equation of a line that you plotted. But with the numbers this gives you, it is linear, which means you can find the slope yourself by doing (y2y1)/(x2x1)

Best ResponseYou've already chosen the best response.0the yintercept is when x is at 0. if you used the calculator I sent you, you should have gotten the equation y=5x+2. also you can see from the data that when x is 0, y is 2. So 2 is the yintercept, and the slope is 5. That tells you that when there are 0 workers, there are 2 units of output

Best ResponseYou've already chosen the best response.0you put in y=5x+2 and not y=2x+5 right?. the site gives it backwards

Best ResponseYou've already chosen the best response.0yeah i accidently put in y=2x+5 instead of y=2+5x xD i got it though, thats right. but Part C..i still dont get that part ..

Best ResponseYou've already chosen the best response.0i think: y= the number of units slope= .....idk..

Best ResponseYou've already chosen the best response.0slope is: number of units/ number of workers so if the slope is 5 then wouldn't that mean there are 5 units output for every worker?

Best ResponseYou've already chosen the best response.0but the slope is 2+5

Best ResponseYou've already chosen the best response.0er, thats what the website gave me.....y=2+5x

Best ResponseYou've already chosen the best response.0y=2+5x is the same as y=5x+2 y=mx+b is the slope intercept form where m=slope, so the slope would be 5

Best ResponseYou've already chosen the best response.0ohhhhhhhhhh, so then slope represents the number of unit outputs per worker..right?
