Transcribed Image Text:Problem 1:
The researchers were inspired by an article they read online (http://www.news-medical.net/news/20140829/Statistical-
analysis-finds-correlation-between-high-BMI-cigarette-smoking-in-teens.aspx). They run their own pilot study to estimate
the relationship between the teens' BMIs and their monthly smoking habits (measured by number of cigarettes smoked in
the past week). They would like to use their data to quantify the relationship between smoking habits (predictor) and BMI
(outcome). From previous research, they estimate that variables are approximately normally distributed and have a linear
relationship.
They collected the following data:
Number of cigarettes
smoked in past week
18
25
7
0
35
BMI
25
26
21
23
32
Expert Solution
Step 1
Given data:
| Number of cigarettes smoked in past week | BMI |
| 18 | 25 |
| 25 | 26 |
| 7 | 21 |
| 0 | 23 |
| 35 | 32 |
