2. Cardiovascular diseases (CVDS) are the number 1 cause of death globally, taking anestimated 17.9 million lives each year, which accounts for 31% of all deaths worldwide.Four out of 5CVD deaths are due to heart attacks and strokes, and one-third of thesedeaths occur prematurely in people under 70 years of age. Heart failure is a commonevent caused by CVDS and the following dataset contains 11 features that can be usedto predict a possible heart disease.

The National Center for Health Statistics (NICH) published a report entitled Health, Pakistan, containing extensive information on major trends in the health of Pakistanis. Data are provided for the Pak population as a whole and for specific ages, sexes and races. The NICH report indicated that in 2012 Pakistanis paid an average of Rs.3,302 per month on health care and prescription drugs. An investigator hypothesizes that in 2015 expenditures have increases primarily due to the availability of generic drugs. To test the hypothesis, samples of 100 Pakistanis are selected and their expenditures on health care and prescription drugs in 2015 are measured. The sample data are summarized as follows: n=100, R =Rs3,390 and s=Rs890. Is there statistical evidence of increased in expenditures on health care and prescription drugs in 2015? Is the sample mean of Rs.3,390 evidence of a true increase in the mean or is it within chance fluctuation?
Q.No.1. Read the following passage and observe the word length of each word. Make a frequency distribution of word length. "Statistics play an intrinsic role in computer science and vice versa. Statistics is used for data mining, speech recognition, vision and image analysis, data compression, artificial intelligence, and network and traffic modeling. A statistical background is essential for understanding algorithms and statistical properties that form the backbone of computer science. Typically, statistical approach to models tends to involve stochastic (random) models with prior knowledge of the data. The computer science approach, on the other hand, leans more to algorithmic models without prior knowledge of the data. Ultimately, these come together in attempts to solve problems."
HDI revisited The United Nations DevelopmentProgramme (UNDP) uses the Human Development Index (HDI) in an attempt to summarize in one number the prog-ress in health, education, and economics of a country. The number of phone subscribers per 100 people is positivelyassociated with economic progress in a country. Can thenumber of phone subscribers be used to predict the HDI?Here is a scatterplot of HDI against phone subscribers:a) Explain why fitting a linear model to these data mightbe misleading.b) If you fit a linear model to the data, what do you think ascatterplot of residuals vs. predicted HDI will look like?

A study published in JAMA in 2004 examined past results of other studies on bariatric surgery. Bariatric surgery is done to replace the size of the stomach in various ways. It is typically used on only obese patients, and one the traditional form of the surgery, gastric bypass has a 1% mortality (death) rate caused by surgery. However, in the studies reporting on the effects of the surgery on Type ll diabetes, 1417 of 1846 diabetic patients recovered completely from diabetes after surgery. These patients no longer need medication like insulin (which is injected into the skin) or pills to help manage blood sugar. In a study released a decade later, the percentage of patients who recover from diabetes has increased 80%. Using confidence intervals determine whether this is a significant change from the 2004 data. Use n=2000

A study investigated the joint effects of sleep quality and sleep duration on the development of coronary heart disease (CHD). A total of 60,586 individuals aged 40 and older with no current or prior history of CHD were enrolled into the study. A self-administered questionnaire was used to collect information on sleep quality and duration at the start of the study, and 43,910 participants reported getting ³6 hours of sleep per day. Participants were followed for approximately 12 years, for a total of 152,000 person-years among those getting <6 hours sleep/day and 527,000 person-years among those getting ³6 hours sleep/day. Out of 2,740 participants who developed CHD throughout follow-up, 721 participants reported getting <6 hours of sleep per day at baseline. Question 10: What is the incidence rate of coronary heart disease among all participants in the study?
In 2015, over 30,00030,000 Americans died from opioid overdoses, and the number of inpatient stays and emergency visits to hospitals related to opiods increased dramatically compared to previous years. The National Institutes of Health (NIH) have partnered with the Healthcare Cost and Utilization Project (HCUP) to gather data on opioid-related deaths and hospitalizations. These data include information about inpatient stays, emergency department visits, age, sex, income, and opiod-related use. For a given patient admitted to a hopsital for an opioid-related event, identify which of these events are disjoint.
Hutchinson-Gilford progeria syndrome is a rare genetic condition that produces rapid aging in children. In individuals with this syndrome, cardiovascular disease is a common cause of death in the teenage years. A clinical study examined the effect of treatment with the drug lonafarnib on a number of physiological outcomes. The researchers measured the pulse wave velocity (PWV) of 18 children diagnosed with progeria and recruited worldwide. The study reports that the mean PWV of 18 children diagnosed with progeria is 12.44 m/s, and the standard deviation is 3.638 m/s. Assuming that PWV is normally distributed, is there significant evidence that the mean PWV of children with progeria is abnormally high (i.e. greater than 6.6 m/s)? Let � (pronounced as "mu") be the true mean PWV of children with progeria. What are the two competing hypotheses? ["", "", "", ""] What is the test statistic? ["", "", "", ""] What is the p value?

toto In physiology, an objective measure of aerobic fitness is how efficiently the body can absorb and use oxygen (oxygen consumption). A physiologist, Dr. Castillejo, conducted a research wherein subjects participated in a predetermined exercise run of 1.5 miles. Measurements of oxygen consumption as well as several other variables such as age, gender, runtime, resting and maximum pulse rates, and weight were recorded from 50 randomly selected gym members. Dr. Castillejo is interested in determining whether any of these other variables can help predict oxygen consumption. She believes that a possible link between these factors will help her determine how to improve the health of her gym members. Help Dr. Castillejo in developing a proposal for the improvement of her gym members' health condition. The variables are described below. gender- either male or female runtime-time to run 1.5 miles (in min) age - age of the gym member in years weight-weight of the gym member (in kg) oxygen…

If you had a morbidly obese relative with diabetes what would you tell him or her about bariatric surgery? Explain. Would you recovered it? Why/ why not?
A team of epidemiologists at the Mayo Clinic wanted to find whether there is an association between obesity and cardiovascular disease (CVD). They conducted a prospective cohort study following obese and non-obese individuals who were free of CVD at the beginning of study for five years. The investigators were also interested in assessing age as a potential confounder, effect modifier, or both. Use the data below to answer the accompanying questions. CVD No CVD Total Obese 10 90 100 Not Obese 35 465 500 Total 45 555 600 CVD No CVD Total Obese 36 164 200 Not Obese 25 175 200 Total 61 339 400 1. Compute the appropriate measure of association for those who were less than age 50. 2. Compute the appropriate measure of association for those who were older or equal to age 50. 3. Compute the crude measure of association? 4. List three attributes that age must satisfy before it could…
