The regression equation is (d) log(y) = 0.064x + 1.706

How to determine the regression equation?

The table of values is given as:

x   2   3   4   5   6

y   73  77  85  101  133

Calculate the logarithm of the y values.

So, we have:

x          2   3   4   5   6

log(y)   1.86  1.89  1.93  2  2.12

Next, we enter the above values in a regression calculator.

From the calculator, we have the following summary:

  • Sum of X = 20
  • Sum of Y = 9.8
  • Mean X = 4
  • Mean Y = 1.96
  • Sum of squares (SSX) = 10
  • Sum of products (SP) = 0.63

The regression equation is then represented as:

log(y) = bx + a

Where:

b = SP/SSX = 0.64/10 = 0.064

a = MY - bMX = 1.96 - (0.064*4) = 1.706

So, we have:

log(y) = 0.064x + 1.706

Hence, the regression equation is (d) log(y) = 0.064x + 1.706
