Question
A veterinary research center analyzed data the body and heart weight (both in grams) of
certain animal. The researchers want to understand if there is a significant linear relationship
between heart weight and total body weight. Use Excel or other software to answer the
following.
Click to view and copy/download the data on body and heart weights.
a) Using heart weight as the independent variable, the linear regression can be estimated as:
X.
y3=
(Round b, and b, to the nearest integer and one decimal place, respectively, including any
zeros in the decimal.).
b) The researchers should test the hypothesis Ho: B, = 0 against H, B, ±0, which is a
two-tailed test.
one-tailed test.
C) The t value for the test is
(Round to two decimal places, including any zeros.)
d) The p-value for the test is
(Round to three decimal places including any zeros.)
e) There
V sufficient evidence to reject H and suggest a significant linear relationship
between heart and body weights.
