Chapter 1: Problem 8

A consumer group conducts crash tests of new model cars. To determine the severity of damage to 2006 Mazda 6s resulting from a 10 -mph crash into a concrete wall, the research group tests six cars of this type and assesses the amount of damage. Describe the population and sample for this problem.

Short Answer

Expert verified
The population in this scenario is all new model 2006 Mazda 6s cars, while the sample is the six new model 2006 Mazda 6s cars that were specifically tested by the research group.

Step by step solution

01

Identify the Population

In this case, the population can be determined as all new model 2006 Mazda 6s cars. This is because the population is referred to as the complete set of items - in this case, cars - that share at least one property in common - being subjected to a crash test.
02

Identify the Sample

The sample in this problem is the six new model 2006 Mazda 6s cars that the research group specifically tested. This forms a part of the population which is being studied and analyzed.

USA Today compared the average graduation rates for male football and basketball scholarship players at top-ranked universities. The graduation rates were expressed as a difference between the graduation rate for scholarship athletes and the university's overall graduation rate for men. A positive number means that the athletes had a graduation rate higher than the overall graduation rate \((+2\) means \(2 \%\) higher) and a negative number means the athletes had a lower graduation rate than the overall graduation rate \((-2\) means \(2 \%\) lower). Using the same scale, construct a dotplot of the graduation rate differences for football players and a dotplot for the graduation rate differences for basketball players. Comment on the similarities and differences in the two plots. $$ \begin{array}{lr} \text { Football } \\ \hline & \begin{array}{l} \text { Difference } \\ \text { from overall } \\ \text { graduation } \end{array} \\ \text { School } & \text { rate } \\ \text { Nebraska } & +8 \\ \text { Kansas State } & +6 \\ \text { Arizona State } & 0 \\ \text { Penn State } & -2 \\ \text { Georgia } & -2 \\ \text { Purdue } & -4 \\ \text { Iowa } & -4 \\ \text { Florida State } & -9 \\ \text { Southern Cal } & -10 \\ \text { Miami } & -11 \\ \text { LSU } & -12 \\ \text { Notre Dame } & -13 \\ \text { Ohio State } & -13 \\ \text { Tennessee } & -13 \\ \text { Virginia } & -14 \\ \text { N.C.

The paper "Profile of Sport / Leisure Injuries Treated at Emergency Rooms of Urban Hospitals" (Canadian Journal of Sports Science [1991]: \(99-102\) ) classified noncontact sports injuries by sport, resulting in the following table: $$ \begin{array}{lc} \text { Sport } & \begin{array}{l} \text { Number of } \\ \text { Sport Injuries } \end{array} \\ \hline \text { Touch football } & 38 \\ \text { Soccer } & 24 \\ \text { Basketball } & 19 \\ \text { Baseball/softball } & 11 \\ \text { Jogging/running } & 11 \\ \text { Bicycling } & 11 \\ \text { Volleyball } & 17 \\ \text { Other } & 47 \\ & \\ \hline \end{array} $$ Calculate relative frequencies and draw the corresponding bar chart.

For each of the following situations, give a set of possible data values that might arise from making the observations described. a. The manufacturer for each of the next 10 automobiles to pass through a given intersection is noted. b. The grade point average for each of the 15 seniors in a statistics class is determined. c. The number of gas pumps in use at each of 20 gas stations at a particular time is determined. d. The actual net weight of each of 12 bags of fertilizer having a labeled weight of \(50 \mathrm{lb}\) is determined. e. Fifteen different radio stations are monitored during a 1-hr period, and the amount of time devoted to commercials is determined for each.

Give a brief definition of the terms population and sample.

A building contractor has a chance to buy an odd lot of 5000 used bricks at an auction. She is interested in determining the proportion of bricks in the lot that are cracked and therefore unusable for her current project, but she does not have enough time to inspect all 5000 bricks. Instead, she checks 100 bricks to determine whether each is cracked. Describe the population and sample for this problem.
