6. Dr. Castillejo feels that maximum pulse rate during the run is a good predictor in explaining the oxygenconsumption in the blood stream. He asserts that if pulse rate at the end of the run increased, then theoxygen consumption will also increase, hence his/her heart is functioning well. Based on the Rcommander output below, check if the data on oxygen consumption and maximum pulse rate (from152bpm to 196 bpm) support Dr. Castillejo's assertion. Make sure to interpret all necessary estimates.Give the expected oxygen consumption if maximum pulse rate is 160 bpm. Also, provide a measure thatreports the adequacy of the model.R COMMANDER OUTPUT1m (formula = oxygen.consumption maximum.pulse, data = aerobic)Coefficients:Estimate Std.

Brunt, Rhee, and Zhong (2008) surveyed 557 undergraduate college students to examine their weight status, health behaviors, and diet. Using body mass index (BMI), they classified the students into four categories: underweight, healthy weight, overweight, and obese. They also measured dietary variety by counting the number of different foods each student ate from several food groups. Note that the researchers are not measuring the amount of food eaten, but rather the number of different foods eaten (variety, not quantity). Nonetheless, it was somewhat surprising that the results showed no differences among the four weight categories that were related to eating fatty and/or sugary snacks.Suppose a researcher conducting a follow up study obtains a sample of n = 25 students classified as healthy weight and a sample of n = 36 students classified as overweight. Each student completes the food variety questionnaire, and the healthy-weight group produces a mean of µ = 4.01 for the fatty,…

A veterinarian wishes to compare the number of times race horses are reported to be lame during a 12‑month period, as compared with similar horses that are not raced. The veterinarian is particularly interested in whether the exercise schedule used in racing contributes to lameness, rather than the total amount of exercise. The veterinarian feels horses to be compared should be similar with regard to age, breed, and the number of weekly hours spent exercising. Which of the given study types should be used? Group of answer choices a. A matched design in which a race horse is chosen, and a horse that is the same age, the same breed, and exercised the same number of hours is chosen for comparison. b. A horse is chosen and raced for one year, but is not raced the next year. c. A group of race horses is chosen and then, from a nearby barn, a group of horses that do not race is chosen. d. None of the answer options are correct.
Over a nine-month period, OutdoorGearLab tested hardshell jackets designed for ice climbing, mountaineering, and backpacking. Based on the breathability, durability, versatility, features, mobility, and weight of each jacket, an overall rating ranging from 0 (lowest) to 15 (highest) was assigned to each jacket tested. The following data show the results for 10 top-of-the line jackets (OutdoorGearLab website, February 27, 2013). Answer questions 10-14.

The National Collegiate Athletic Association (NCAA) requires colleges to report the graduation rates of athletes. Here are data from a Big Ten university’s report. The graduation rates were 37 of 45 female athletes and 58 of 102 male athletes. Is there evidence that a smaller proportion of male athletes than female athletes graduate within six years?
The Federal Bureau of Investigation (FBI), as part of its internal security mission, serves as a database for all the reported crimes committed in the United States. One question that might be of interest is does having more police officers reduce the number of homicides? To investigate this claim, the 2013 data from the twenty largest municipal cities was supplied by the FBI's Uniform Crime Report. Below are two observations from the dataset: > head (cities) City Pop Homicides Police Density MedHome Mayor 1 New York 8175.133 335 4.2595 27016.30 5.5390 1 2 Chicago 2695.598 414 4.4309 11843.58 1.8310 The variables included in the study are: Name of city Population of city in 1,000s of people Number of homicides in the year 2013 Number of police officers per 1,000 people Number of people per square mile Median home price in $100,000 1 if city has a "Strong Mayor" form of government; 0 if not City Рор Homicides Police Density MedHome Мayor Model: log(u;) = Bo + B1Police; + B2MedHome; +…
A major home improvement store conducted its biggest brand recognition campaign in the company’s history. A series of new television advertisements featuring well-known entertainers and sports figures were launched. A key metric for the success of television advertisements is the proportion of viewers who “like the ads a lot”. A study of 1,189 adults who viewed the ads reported that 230 indicated that they “like the ads a lot.” The percentage of a typical television advertisement receiving the “like the ads a lot” score is believed to be 22%. Company officials wanted to know if there is evidence that the series of television advertisements are less successful than the typical ad (i.e. if there is evidence that the population proportion of “like the ads a lot” for the company’s ads is less than 0.22) at a 0.01 level of significance. Test hypothesis ?
