I have a big problem with this question:
A store that sells soda has noticed that the variation of selling is big
depending on the temperature. To get a opinion about the relationship
between the mean temperature and the sell of soda each day they make a
multiplicative regressionmodel.
sell(y) temperature(t)
23 7
25 8
32 12
35 12
35 12
40 14
48 19
51 21
70 25
question: You shall make a multiplicative regressionmodel for the sell
according to this furmula
b1
y=bo x t
I have tried to first make a regression model like:
y= bo + b1 x t
then I get bo=34.55
bi=0.403
But when I try t make logarytm of these it gets too high
34.55
bo= log bo= 10 =3.548133892E34
What do I do wrong?
How should I solve this question?
