Chapter 5, Problem 16CRE
In the article “Reproductive Biology of the Aquatic Salamander Amphiuma tridactylum in Louisiana” (Journal of Herpetology [1999]: 100–105). 14 female salamanders were studied. Using regression, the researchers predicted y = Clutch size (number of salamander eggs) from x = Snout-vent length (in centimeters) as follows:
For the salamanders in the study, the
- a. What is the value of the y intercept of the least-squares line?
- b. What is the value of the slope of the least-squares line? Interpret the slope in the context of this problem.
- c. Would you be reluctant to predict the clutch size when snout-vent length is 22 cm? Explain.

A medical student at a community college in city Q wants to study the factors affecting the systolic blood pressure of a person (Y) Generally, the systolic blood pressure
depends on the BMI of a person (B) and the age of the person A. She wants to test whether or not the BMI has a significant effect on the systolic blood pressure, keeping the
age of the person constant. For her study, she collects a random sample of 125 patients from the city and estimates the following regression function:
Y= 15.50 + 0..90B+1.15A.
(0.55)
(0 40)
The test statistic of the study the student wants to conduct (Ho: B, = 0 vs. H, B, #0), keeping other variables constant is.
(Round your answer to two decimal places.)
At the 5% significance level, the student will
▼ the null hypothesis.
Keeping BMIl constant, she now wants to test whether the age of a person (A) has no significant effect or a positive effect on the person's systolic blood pressure.
So, the test statistic associated with the one-sided test the…
Do wearable devices that monitor diet and physical activity
help people lose weight? Researchers had 237 subjects who
were already involved in a program of diet and exercise use
wearable technology for 24 months. They measured their
weight (in kilograms) before using the technology and 24
months after using the technology.
The 237 differences in weight (weight after 24 months
minus weight before using the wearable technology) had
x = -3.5 and s = 7.8.
Let u be the mean weight difference.

A researcher is interested in testing the relationship between smoking and BMI (kg/m2) in adults aged 30-45. In order to test this association, the researcher divides smoking into currently more than a pack a day, currently less than a pack a day, and never smokers. The following table represents the BMIs for each participant enrolled by their respective smoking category.
