Question
Miniature horses are a special breed of very very small horse. A minuature horse breeder is interested in the relationship between the size (height) of a miniature horse and the price it sells for. She decides to fit the simple linear regression model:
E(y) = β0 + β1x
where y = selling price of miniature horse (in $) and x = height of horse (cm).
What set of hypotheses would you test to determine whether selling price is linearly related to height of miniature horse?
Select one:
a.H0: β0 > 0, Ha: β0 = 0
b.H0: β1 ≠ 0, Ha: β1 = 0
c.H0: β1 = 0, Ha: β1 ≠ 0
d.H0: β0 = 0, Ha: β0 ≠ 0
