The table gives Sweden's nuclear power generation data in billions of kilowatt-hours. Let x = 5 represent 1980, x = 10 represent 1985, and so on.
Energy produced |25.3|55.8|65.2|66.5|
(a) Find a natural logarithm regression equation for the data.
(b) Predict when Sweden's nuclear power generation will reach 85 billion kilowatt-hours.
Ok, so in my calculator i have (I think) found the ln regression equation, which is Y= a+blnx
So the equation should be -20.9 + 30.8lnx correct?
and to predict for (b), I need to make a graph of the data, but I am unsure on how to do that, could someone help please?
Thanks a bunch!
