Consider the exponential prediction equation Yhat abX The v

Consider the exponential prediction equation Y(hat) = ab^X The values in logarithmic form are log a - 1 7782, log b = 1004 What is the predicted value of Y for X - 9?

Solution

As

y = a b^X

and

a = 10^1.7782 = 60.00673539

b = 10^0.1004 = 1.260085459

Then

y = 60.00673539*(1.260085459^9)

y = 480.6179645 [ANSWER]
