Chapter 3, Problem 70PS
The manufacturer of Boston and Vermont asphalt shingles provides its customers with a 20-year warranty on most of its products. To determine whether a shingle will last as long as the warranty period. accelerated-life testing is conducted at the manufacturing plant Accelerated-life testing exposes a shingle to the stresses it would be subject to in a lifetime of normal use via an experiment in a laboratory setting that takes only a few minutes to conduct in this test. a shingle is repeatedly scraped with a brush for a short period of time. and the shingle granules removed by the brushing are weighed (in grams). Shingles that experience low amounts of granule loss are expected to last longer in normal use than shingles that experience high amounts of granule loss. In this situation. a shingle should experience no more than 0.8 gram of granule loss if it is expected to last the length of the warranty period. The file Granule contains a sample of 170 measurements made on the company's Boston shingles and 140 measurements made on Vermont shingles.
a. List the
b. Construct side-by-side boxplots for the two brands of shingles and describe the shapes of the distributions
c. Comment on the ability of each type of shingle to achieve a granule loss of 0.8 gram or
less.

The annual number of burglaries in a town rose by 50% in 2012 and fell by 10% in 2013. Hence the total number of burglaries increased by 40% over the two year period.
What is the mistaken assumption here?
Why is that assumption incorrect?
An experimenter wants to study the relationship between type of milk and infant growth in underdeveloped countries. She randomly assigns 300 infants to either a breast-feeding group or an infant formula group. She then weighs the infants every three days for the first four weeks of life.

She randomly divides twenty-four students into three groups of eight. All students study a passage of text for 30 minutes. Those in group 1 study with background sound at a constant volume in the background. Those in group 2 study with noise that changes volume periodically. Those in group 3 study with no sound at all. After studying, all students take a 10 point multiple choice test over the material.

The amber contained the remains of an beetle. Curious to know whether the gem is genuine or not, the student takes the sample to the laboratory and determines the concentration of Carbon-14 (A = 5730 years). After extracting a piece of the trapped beetle with a fine drill, instrument analysis reported that the concentration of Carbon-14 is now only 94%. If there was 100% Carbon-14 when the beetle was trapped, how old is the gem and is it genuine? (Trivia: Amberification is a polymerization process that takes several millions of years. The "youngest" amber is around 16 million years old and can be found in the Dominican Republic). 23,000 years old (counterfeit) O 51 million years old (genuine) 23 million years old (genuine) O 510 years old (counterfeit)arrow_forward
- virus is that these cells die. In this study of the effectiveness of a new anti-viral drug on HIV, 20 HIV-positive patients had their CD4 counts recorded (“Baseline”) and then were put on a course of treatment with this drug. After using the drug for one year, their CD4 counts were again recorded (“OneYear”). The aim was to show that patients taking the drug had increased CD4 counts which is not generally seen in HIV-positive patients.

Different formulas are used for different colleges and majors. Suppose that a student is applying to a university with an intended major in civil engineering. Also suppose that for this college and this major, the following model is used to predict first term GPA. GPA = a + b(ACT) a = 0.6 b = 0.2 (a) In this context, what would be the appropriate interpretation of the value of a? The value of a is the predicted ACT score of a student who has a 0 GPA. There is not enough information to know how to interpret the value of a. The value of a represents the change in predicted GPA associated with an increase of 1 in ACT score. The value of a represents the change in predicted GPA associated with an decrease of 1 in ACT score. The value of a is the predicted GPA of a student who scored a 0 on the ACT.
