Multiple Choice: Choose the correcr answer

A. Find a regression line relating systolic blood pressure to weight

B. Test for significance of regression using α = 0.05

C. Estimate the correlation coefficient

Choices:

  a.

y = -25.294 + 1.426x

Regression model is significant

r = 0.77349

  b.

y = 69.104 + 0.419x

Regression model is significant

r = 0.77349

  c.

y = 69.104 + 0.419x

Regression model is not significant

r = 0.5982

  d.

y = 5.50 + 6.73x

Regression model is significant

r = 0.77349

  e.

y = 69.104 + 0.419x

Regression model is not significant

r = 0.77349
