(a) As the class wondered if they could <em>predict the father's height</em>, when they<em> know the son's height</em>
Explanatory variable = son's height
Response variable = father's height
(even though this is contrary to real-life, where the father's height would be used to predict the son's height)
(b) **see first attachment**
(c) The association is positive since the father's height increases as the son's height increases.
(d) **see second attachment**
Outlier = Paul (64.5, 73)
This point is far away from the majority of points on the scatter plot.
If we add a regression line to the scatter plot, we can see that this data point is the farthest from the regression line.
Answer:
0.006% of people had a reaction
Step-by-step explanation:
1,500 tried it -----> 9 had a reaction
9/1,500
Divide both numerator and denominator by 3
3/500
Multiply by 2 to get the fraction out of 1000
6/1000
Divide by 10 to get the fraction out of 100
0.6/100
0.006%
