Answer:
A)there is a strong positive correlation
B)A function that best fits the data is
C)Slope indicates the rate of change of Number of products per employee
y intercept indicates number of products when number of employees are 0
Step-by-step explanation:
Number of employees (x) 0 25 50 75 100 125 150 175 200
Number of products (y) 10 160 310 460 610 760 910 1060 1210
Part A: Is there any correlation between the number of employees in the plant and the number of products produced yearly?
Mean of x values =
Mean of y values =
N =No. of observations= 9
R Calculation
So, there is a strong positive correlation
B: Write a function that best fits the data.
Regression Equation = ŷ = bx + a
So, a function that best fits the data is
C)What does the slope and y-intercept of the plot indicate?
Slope indicates the rate of change of Number of products per employee
y-intercept indicates the y-coordinate of a point where a line, curve, or surface intersects the y-axis.
So, y intercept indicates number of products when number of employees are 0 .
