13. A new strong painkiller is tested on eight arthritis sufferers. Each one is given a different dose of the drug (in mg), and the duration (number of hours) that the drug is effective is measured. The data show that the larger the dosage, the longer the duration that the drug is effective. A data summary is given below. We want to predict the duration (number of hours) the drug is effective based on dosage. What is the least-squares regression line? mean standard deviation Dosage 0.625 0.4301 Hours (Duration) 4.875 2.3566 r2 = 0.6064 A. predicted hours 3.59 + 4.03*dosage B. predicted hours = 2.21 + 4.27*dosage C. predicted hours = 0.57 + 4.11*dosage D. predicted hours = 0.24 + 4.89*dosage

. Students may be classified as having a math dysfunction—and not have to take statistics—if they score below the 25th percentile on a diagnostic test. The m of the test is 75 and sX 10. Approximately what raw score is the cutoff score needed to avoid taking statistics?
C6. The GSS 2014 asked respondents to identify what was important for "truly bemg American." When asked "How important to have American ancestry?" answers were measured on a 4-point scale: 1 = very important, 2 = fairly important, 3 = 1ot important, and 4 = not important at all. We selected a sample of 20 GSS respondents and present their individual responses.

O Macmillan Learning Many young men in North America and Europe (but not in Asia) tend to think they need more muscle to be attractive. One study presented 200 young American men with 100 images of men with various levels of muscle. Researchers measure level of muscle in kilograms per square meter of body surface area (kg/m²). Typical young men have about 20 kg/m². Each subject chose two images, one that represented his own level of body muscle and one that he thought represented "what women prefer." The mean gap between self-image and "what women prefer" was 2.35 kg/m². Suppose that the "muscle gap" in the population of all young men has a Normal distribution with standard deviation 2.5 kg/m². Give a 90% confidence interval for the mean amount of muscle young men think they should add to be attractive to women. (They are wrong: women actually prefer a level close to that of typical men.) Give your answers to four decimal places. lower limit: upper limit: Chi-Fu Jeffrey Yang, Peter…
whether cross-sectional, retrospective, or prospective is used. Rats with cancer are divided into two groups. One group receives 5 mg f mediation that is thought to fight cancer, and the other receives 10 mg. After 2 years, the spread of the cancer is measured.
Refer to Exercise 3. In the last 50 samples, there were a total of 622 defective items. The largest number of defectives in any sample was 24, while the smallest number was 6. Is this enough information to determine whether the process was out of control at any time during the last 50 samples? If so, state whether or not the process was out of control. If not, state what additional information would be required to make the determination.
n a 2014 study, Michael Smith arranged to be stung by bees repeatedly on 25 locations over 38 days to record the relative pain experienced by each sting in each body area. A scale pain ratings of 1-10 were used with stings to the forearm defined to be a 5. What is the population of this study?

An outbreak of the deadly Ebola virus in 2002 and 2003 killed 91 of the 95 gorillas in 7 home ranges in the Congo. To study the spread of the virus, measure " distance" by the number of home ranges separating a group of gorillas from the first group infected. Here are data on distance and number of days until deaths began in each later group: Distance xx 2 5 4 4 4 6 Days yy 4 21 29 40 47 49 Use a calculator or software to find the following values.

The data used is from college campuses. The variables used in the analysis below include: crime, total campus crime; enroll, total enrollment; police, employed officers. Use the estimated OLS models to answer the questions below: Model A: In(crime) = -6.631 + 1.270ln(enroll), (1.034) (.110) .5804 n = 97; R² = Model B: In(crime) = -4.794+.923ln(enroll) +.516ln(police), (.144) (.149) (1.112) n = 97; R² = .632 Using Model A, test the null hypothesis that elasticity of crime with respect to enrollment is unit elastic, i.e. equal to one (against a two-sided alternative). What is the conclusion of your test using a significance level of .01? Reject Fail to reject O Not enough information.
A team of pharmacists was researching two sleeping pills they were developing. 20 individuals took part in the study and they were randomly divided into two groups and one group received sleeping pills 1 and the other group sleeping pills 2. The pharmacists then measured how long the individuals slept after ingestion. The data can be seen below: SLEEPING MEDICINE 1 SLEEPING MEDICINE 2 9.2 6.8 7.4 6.2 10.1 8.1 6.8 7.2 9.1 5.8 8.2 8.8 9.2 6.2 8.8 7.1 7.6 7.3 8.8 6.9 Let us now assume that the assumptions that need to apply can be used in a study such as this to confirm the efficacy of the drugs. Examine with an appropriate hypothesis test whether there is a difference in mean sleep duration after taking the two drugs. In the event that you need to check whether the distribution in the two groups can be assumed to be the same, it is sufficient to use the rule of thumb to determine this. Sleep duration can be assumed to follow a normal distribution. Use a = 0.05. Show all six steps. Please…
