a)Find the multiple regression equation using all three explanatory variables. Assume that X₁is age, X₂is weight and X₃is height. Give your answers to 3 decimal places.

y^=_____+______age +______weight +________height

b)At a level of significance of 0.05, the result of the F test for this model is that the null hypothesis_______rejected.

For partsc)andd), using the data, separately calculate the correlations between the response variable and each of the three explanatory variables.

c)The explanatory variable that is most correlated with heart rate is:

1)age

2)weight

3)height

d)The explanatory variable that is least correlated with heart rate is:

1)age

2)weight

3)height

e)The value of R²for this model, to 2 decimal places, is equal to____

f)The value of s_efor this model, to 3 decimal places, is equal to______

g)Construct a new multiple regression model by removing the variable height. Give your answers to 3 decimal places.

The new regression model equation is:

y^=______+age +_____weight

h)In the new model compared to the previous one, the value of R²(to 2 decimal places) is:

1)increased

2)decreased

3)unchanged

i)In the new model compared to the previous one, the value of s_e(to 3 decimal places) is:

1)increased

2)decreased

3)unchanged
