Chapter 3.1, Problem 46PE
Gas mileage is tested for a car under different driving conditions. At lower speeds, the car is driven in stop-and-go traffic. At higher speeds, the car must overcome more wind resistance. The variable x given in the table represents the speed (in mph) for a compact car, and
represents the gas mileage (in mpg).
x | 25 | 30 | 35 | 40 | 45 |
|
22.7 | 25.1 | 27.9 | 30.8 | 31.9 |
x | 50 | 55 | 60 | 65 |
|
30.9 | 28.4 | 24.2 | 21.9 |
a. Use regression to find a quadratic function to model the data.
b. At what speed is the gas mileage the greatest? Round to the nearest mile per hour.
c. What is the maximum gas mileage? Round to the nearest mile per gallon.

Hookworms are parasitic nematodes that live in the intestines of a host. Hookworms do their damage (often fatally) by draining blood
from the intestinal wall. The data below correlate the number of hookworms and the amount of blood lost by that number of worms.
(Include units below if applicable. If necessary, use a separate sheet of paper for 6c and 7c.)

- The accompanying table shows the height and weight of five football players in training camp. The body mass index (BMI) is used to assess the relative amount of fat in a person's body. If w is weight in pounds and h is height in inches, then BMI = 703wh. Some physicians consider your body fat abnormal if your BMI satisfies BMI-23>3. Which of the five players does not have abnormal body fat? does not have abnormal body fat. Player D Player B Player C Player E Player A ..

One aspect of the study was to develop a model that could be used to predict a bear's weight (since it is not practical to weigh bears in the field). One variable thought to be related to weight is the length of the bear. The accompanying data represent the lengths and weights of 12 American black bears. Complete parts (a) through (d) below. Click the icon to view the data table. Click the icon to view the critical values table. ..... (a) Which variable is the explanatory variable based on the goals of the research? O A.

- A researcher wants to determine if the exam scores of the students are dependent on the length of time spent in studying the subject. Ten students in a certain class were taken and the results are shown in the table below where X is the time spent in studying the subject in hours and Y is the examination scores. (Copy-paste the data and run the analysis using MS Excel). X (time) Y (score) 1.5 80 3.0 83 1.25 83 0.5 70 3.5 85 2.5 75 1.0 70 3.0 90 2.5 86 4.0 91 Predict the examination score (rounded to the nearest integer) of a student who spends 2 hours in studying the subject.arrow_forwardDetermine the level of measurement of the variable.SLO #1C: the musical instrument played by a music studentarrow_forwardFind the absolute and percent relative uncertaintyarrow_forward
