In Great Britain during the 1800 s political and social reforms changed people's lives for the better.

In an essay, analyze the causes and effects of British reforms during the 1800 s. To provide support for your essay, use specific examples from the chapter and from other research sources if needed.

A researcher reported that the typical teenager needs 9.3 hours of sleep per night but gets only 6.3 hours. By the end of a 5-day school week, a teenager would accumulate about 15 hours of "sleep debt." Students in a high school statistics class were skeptical, so they gathered data on the amount of sleep debt (in hours) accumulated over time (in days) by a random sample of 25 high school students. The resulting least-squares regression equation for their data is

$$\widehat{Sleep debt} = 2.23 + 3.17(days).$$

(a) Interpret the slope of the regression line in context. (b) Are the students' results consistent with the researcher's report? Explain.

Redeeming coupons from text messages. Many companies now use text messaging on cell phones as a means of marketing their products. One way to do this is to send a redeemable discount coupon (called an m-coupon) via a text. The redemption rate of m-coupons-the proportion of coupons redeemed-was the subject of an article in the Journal of Marketing Research (October 2015). In a two-year study, over 8,000 mall shoppers participated by signing up to receive $\mathrm{m}-$ coupons. The researchers were interested in comparing the redemption rates of $\mathrm{m}$-coupons for different products. In a sample of 2,447 m-coupons for products sold at a milkshake store, 79 were redeemed; in a sample of $6,619 \mathrm{~m}$-coupons for products sold at a donut store, 72 were redeemed. Assume the true difference between redemption rates must exceed $.01$ (i.e., $1 \%$ ) for the researchers to consider the difference to be "practically" significant. Based on the interval, part c, is there a "practically" significant difference between the redemption rates?

The CEO of a company that owns five resort hotels wants to evaluate and compare satisfaction with the five hotels. The company's research department randomly sampled 125 people who had stayed at any of the hotels during the past month and asked them to rate their expectations of the hotel before their stay and to rate the quality of the actual stay at the hotel. Both observations used a rating scale of 0-10, with 0 = very poor and 10 = excellent. The researchers compared the hotels on the gap between prior expectation and actual quality, using the difference score, y = performance gap = (prior expectation score - actual quality score).

State the null and alternative hypotheses for conducting an ANOVA.

Identify the response variable, the factor, and the categories that form the groups.

'' In many cases, withholding the intervention from the control group is ethical since being in the study leaves them just as well off as they would have been had they not participated in the study. However, for vulnerable populations (e.g., students with disabilities) this may not be as straightforward. If researchers have good reason to believe char an intervention will benefit their study participants, denying this intervention to a control group may raise ethical questions. Conducting a pre-post test study addresses this ethical concern by offering the intervention to all study participants.'' -National Center for Technology Innovation. What does this document say about the importance of evaluating how a control group is affected by the research topic?

about the topic and the major issues related to the topic. What major advances have been made with this source of energy? What are the major drawbacks? What are the primary uses for this form of energy at present? Take notes as you conduct your research and continue to generate questions as you learn more.

Atmospheric pressure on Venus is $92 \times 10^{5} \mathrm{N} / \mathrm{m}^{2}$. Suppose that NASA is planning to land a $1.0-\mathrm{m}-$radius spherical research vehicle on Venus. (a) Determine the force on each square centimeter of its surface. (b) What is the buoyant force exerted by the atmosphere on the spherical vehicle?

Conduct on line research to learn more about a recent class action lawsuit. Prepare a report on your findings. In the report, provide details on what company was involved in the lawsuit, the issues of the lawsuit , the types of injuries suffered, the outcome (was there a settlement or remedy, and if so, what was it), and any other pertinent information .

Above the underlined noun in each sentence, write its plural form.

Example 1. My mom and aunt are $\overset{\textit{\color{#c34632}{alumnae}}}{{\underline{\text{alumna}}}}$ of the same college.

Your research paper should prove one thesis, not two $\underline{\text{thesis}}$.

An understanding of cockroach biology may lead to an effective control strategy for these annoying insects. Researchers studying the absorption of sugar by insects feed cockroaches a diet containing measured amounts of a particular sugar. After 10 hours, the cockroaches are killed and the concentration of the sugar in various body parts is determined by chemical analysis. The paper that reports the research states that a 95% confidence interval for the mean amount (in milligrams) of the sugar in the hindguts of the cockroaches is 4.2 $\pm$ 2.3. Does this paper give evidence that the mean amount of sugar in the hindguts under these conditions is not equal to 7 mg? State $\mathrm{H}_0$ and $\mathrm{H}_a$ and base a test on the confidence interval.

Amyloid Fibers in Disease Several small aromatic molecules, such as phenol red (used as a nontoxic drug model), have been shown to inhibit the formation of amyloid in laboratory model systems. A goal of the research on these small aromatic compounds is to find a drug that would efficiently inhibit the formation of amyloid in the brain in people with incipient Alzheimer's disease.
(a) Suggest why molecules with aromatic substituents would disrupt the formation of amyloid.
(b) Some researchers have suggested that a drug used to treat Alzheimer's disease may also be effective in treating type 2 (non-insulin-dependent) diabetes mellitus. Why might a single drug be effective in treating these two different conditions?

Unethical corporate conduct. How complicit are entry level accountants in carrying out an unethical request from their superiors? This was the question of interest in a study published in the journal Behavioral Research in Accounting (July 2015). A sample of 86 accounting graduate students participated in the study. After asking the subjects to perform what is clearly an unethical task (e.g., to bribe a customer), the researchers measured each subject's intention to comply with the unethical request score. Scores ranged from $-1.5$ (intention to resist the unethical request) to $2.5$ (intention to comply with the unethical request). Summary statistics on the 86 scores follow: $\bar{x}=2.42, s=2.84$. Give a practical interpretation of the interval, part a.
