12.117 do e and f for me. and explain please. thanks 12.117 Bus Rapid Transit study. Bus Rapid Transit (BRT) is a adly growing trend in the provision of public transportationin America. The Center for Urban Transportation Research(CUTR) at the University of South Florida conducteda survey of BRT customers in Miami (TransportationResearch Board Annual Meeting, Jan. 2003). Datathe following variables (all measured on a 5-point scawhere 1 very unsatisfied and 5= very satisfied) werecollected for a sample of over 500 bus riders overal satisfaction with BRT (y), safety on bus (x₁), seat avail-ability (x₂), dependability (x3), travel time (x4), cost (xs),information/maps (x6), convenience of routes (x), trafficsignals (xg), safety at bus stops (x9), hours of service (10),and frequency of service (x1). CUTR analysts used stepwiseregression to model overall satisfaction (y).a. How many models are fit at step 1 of the stepwiseregression?b. How many models are fit at step 2 of the stepwiseregression?c. How many models are fit at step 11 of the stepwiseregression?d. The stepwise regression selected the following eightvariables to include in the model (in order of selec-tion): X11, X4, X2, X7, X10, X₁, X9, and x3. Write the equa-tion for E(y) that results from stepwise regression.e. The model, part d, resulted in R2 = .677. Interpretthis value.f. Explain why the CUTR analysts should be cautious inconcluding that the best model for E(y) has been found.gist

Birthweight In 2003 the Journal of the AmericanMedical Association reported a study examining thepossible impact of air pollution caused by the 9/11 attack New York’s World Trade Center on the weight ofbabies. Researchers found that 8% of 182 babies born tomothers who were exposed to heavy doses of soot andash on September 11 were classified as having low birthweight. Only 4% of 2300 babies born in another NewYork City hospital whose mothers had not been near thesite of the disaster were similarly classified. Does thisindicate a possibility that air pollution might be linked toa significantly higher proportion of low-weight babies?a) Was this an experiment? Explain. b) Test an appropriate hypothesis and state your conclu-sion in context. c) If you concluded there is a difference, estimate thatdifference with a confidence interval and interpret thatinterval in context.
10.14 A 1980 study investigated the relationship between the use of OCs and the development of endometrial cancer [9]. The researchers found that of 117 endometrial-cancer patients, 6 had used the OC Oracon at some time in their lives, whereas 8 of the 395 controls had used this agent. Test for an association between the use of Oracon and the incidence of endometrial cancer, using a two-tailed test.
The director of an obesity clinic in a large northwestern city believes that drinking soft drinks contribute to obesity in children. To determine whether a relationship exists between these two variables, she conducts the following pilot study. Eight- 12-year-old male volunteers are randomly selected from children attending a local junior high school. Parents of the children are asked to monitor the number of soft drinks consumed by their child over a one week period. The children are weighed at the end of the week and their weights converted into body mass index (BMI) values. The BMI is a common index used to measure obesity and takes into account both height and weight. An individual is considered obese if they have a BMI value 30. The following data or collected: child. # of soft drinks consumed BMI 1 3 20 2 1 18 3…
A sociologist wants to investigate the question, "Is there a relationship between texting during class and grade-point-average (GPA) among high school seniors in a large district?" Which study design is most appropriate? Before the semester starts, randomly select 40 seniors from each high school who do not text during class. Assign 20 to the texting treatment group (text three or more times during every class meeting) and 20 to the control group (no texting during class). At the end of the semester, obtain each student’s GPA from the appropriate admissions and records office. Compare the GPA of students who routinely text during class to the GPA of students who do not text during class. Before the semester starts, randomly select 40 seniors from each high school who do not text during class. Assign 20 to the texting treatment group (text three or more times during every class meeting) and 20 to the control group (no texting during class). At the end of the semester,…
To examine adolescent substance abuse, Li, Pentz, and Chou (2002) surveyed 1,807 middle school students from 57 schools. The results showed that a greater risk of adolescent substance abuse was associated with increasing numbers of parents and friends who were sub- stance abusers. However, friends’ use did not affect adolescent substance abuse when parents were nonusers. Is this an example of a research design?
A suburban hotel derives its revenue from its hotel and restaurant operations. Theowners are interested in the relationship between the number of rooms occupied on anightly basis and the revenue per day in the restaurant. Below is a sample of 25 days(Monday through Thursday) from last year showing the restaurant income and numberof rooms occupied.
A statistical program is recommended. Jensen Tire & Auto is in the process of deciding whether to purchase a maintenance contract for its new computer wheel alignment and balancing machine. Managers feel that maintenance expense should be related to usage, and they collected the following information on weekly usage (hours) and annual maintenance expense (in hundreds of dollars). Weekly Usage(hours) AnnualMaintenanceExpense 13 17.0 10 22.0 20 30.0 28 37.0 32 47.0 17 30.5 24 32.5 31 39.0 40 51.5 38 40.0 #1) Develop the estimated regression equation that could be used to predict the annual maintenance expense (in hundreds of dollars) given the weekly usage (in hours). (Round your numerical values to two decimal places.) #2) The expected expense of a machine being used 34 hours per week is $ hundred.

Rogers, Farlow, and colleagues (1998) conducted an experiment to investigate whether donepezil improved cognitive function in patients with mild to moderate Alzheimer’s disease (AD). A total of 1,775 patients were randomly assigned to treatment with either donepezil or a placebo (a look-alike pill with no pharmacological effect). Cognitive function, as measured by the Alzheimer’s Disease Assessment Scale (ADAS-cog), was significantly improved in patients taking donepezil compared with the placebo group at weeks 12, 18, and 24. [Source: Rogers, S. L., Farlow, M. R., Doody, R. S., et al. (1998). A 24-week, double-blind, placebo controlled trial of donepezil in patients with Alzheimer’s disease.

A consumer advocacy group wanted to study whether different airline carriers differed in terms of their delayed flights. In particular, the researchers were interested in the relationship between p1, the proportion of Alpha Airlines flights that were delayed at least 15 minutes, and p2, the proportion of Beta Airlines flights that were delayed at least 15 minutes. A random sample of 1,000 Alpha flights and a separate random sample of 1,000 Beta flights found that 67 of the Alpha fights and 160 of the Beta flights were delayed at least 15 minutes. The conditions for inference were checked and verified. Does this set of samples provide strong evidence that Alpha Airlines has a smaller proportion of flights that are delayed at least 15 minutes than Beta Airlines, at the α = 0.05 significance level? Find the z-table here. A. The test statistic is z = –6.56 and the P-value ≈ 0. Since the P-value ≈ 0 < 0.05, there is not sufficient evidence that Alpha Airlines has fewer delayed…
