Question

Oraal Data Proi 28. A developmental psychologist tests the extent to which daily intake of fat (in grams) and amount of exercise (in minutes) can predict health (measured using a body mass index (BMI) scale in which higher scores indicate poorer health). Using the data given here, answer the following questions. Fat (grams) Exercise (minutes) Health (BMI) 34 32 - 10 34 0 50 23 0 15 33 35 28 40 27. 0 0 20 A 60 22

Answer 1

ANSWER:

1. The regression equation is:

y = 1.775 x + 15.575

Slope = 1.775

Intercept = 15.575

2. The plot is:

Health у= 1.775 x+ 15.575 4 6 8 10 12 Fat

3.The p-value is 0.0011

Since the p-value(0.0011) is lessthan the significance level(0.05),we can reject the null hypothesis.

Therefore,we can conclude that the equation is statistically significant.
