The population sampled due to its specific nature i.e., college students, and college graduates would need to be contemplated in regards to the testing results as it is offered as a depiction of the general population.

Heart disease is the leading cause of death among women in the United States. It is estimated that one in four women die from heart disease every year. Women are at a higher risk for heart disease than men because of a lack of knowledge and information. Women often feel the need to care for others before themselves and neglect their own health needs. As mothers, and sisters, and daughters it is important to protect our health for those that depend on us. Heart disease is preventable through knowledge and awareness and taking precautionary steps.

The sample is not a representative of the population. The number of different groups of nurses was not equal. Registered nurses had the biggest number and this made the research biased towards them (Kalisch & Lee, 2011, p. 86). To represent the entire population, the different

Population A and Population B both have a mean height of 70.0 inches with an SD of 6.0. A random sample of 30 people is picked from population A, and random sample of 50 people is selected from Population B. Which sample mean will probably yield a more accurate estimate of its population mean? Why? Despite, both Population A and Population having a mean height of 70.0 inches with an SD of 6.0, Population B will

According to Schutt (2008), sampling is defined as a subset of population used in a study to be a representation of the population as a whole. My final project is a pre-hire assessment which analyzes potential risky pattern behaviors and emotions in the work place. One of the most important considerations related to sampling that will need to be addressed in my final project is defining the population that will be taking the assessment.

4. a) An example of statistics is the statement “Between the ages of 15 and 24, they take their lives five times as often.”

Consider the following scenario in answering questions 5 through 7. In an article appearing in Today’s Health a writer states that the average number of calories in a serving of popcorn is 75. To determine if the average number of calories in a serving of popcorn is different from 75, a nutritionist selected a random sample of 20 servings of popcorn and computed the sample mean number of calories per serving to be 78 with a sample standard deviation of 7.

A population is the entire group to be studied and a sample is a portion of the population.

There are many ways that have been proven to help in preventing cardiovascular diseases; certain exercises and foods in particular. The American Heart Association gives a breakdown, of what you and should be doing to help prevent heart disease, depending on your age. They clearly state, no matter what your age is, you should be eating a healthy diet; this includes, eating a diet low in sodium, saturated fat, and trans fat. Sodium is the salt added into your food. Foods high in sodium are chips, table salt, crackers, pickles, sauces, dressings, and canned foods. Saturated fat is a molecule that has no double bonds, which makes it “stackable” and is considered an unhealthy fat. Foods high in saturated fat are; fatty beef, poultry (with

Schneider reviews American Heart Association spokeswomen, Nieca Goldberg. Goldberg warns that heart disease is the greatest threat among women. She stresses that women must be proactive in their own health, because many physicians don’t recognize women’s heart disease is different than men. The main point is that Schneider highlights what Goldberg emphasizes in her article; women should recognize heart disease symptoms. Goldberg suggests women should use the Mediterranean diet, moderate exercise, and stress management. The article mainly focuses on prevention and warning signs. Schneider highly recommended Goldberg’s writing.

a) Based on a randomly selected group of 500 patients with high cholesterol, it was found that 67% have heart disease. Is this a population or a sample; explain your answer. Raw data is collected from a subset of patient with high cholesterol to determine numbers describing characteristics of the subset (Bennett, Briggis, & Triola, 2009). The raw data collected from the 500 patients is consolidated and summarized to form sample statistics. The raw data and sample statistics are indications that this is a sample (Bennett, Briggis, & Triola, 2009).

A sample is a group of people chosen from a population to embody the population in the experiment, whereas a population is the complete group of the people that pertain to the research subject (Gravetter & Wallnau, 2014). An example of this would be if a researcher was doing a study on children with no siblings in Michigan, the population would be every only child and the sample would be a smaller group of only children to represent the larger group. The reason why a person would not use the entire population is because, although you would get a more accurate result, it also would be too difficult to attain an answer from every only child on Michigan. It is therefore easier to get an estimate to gauge the closest accuracy with a smaller sample set.

(b)How many workers need to be sampled in order to estimate the population proportion of workers who worried about retiring comfortably to within +/- 0.02 with 95% confidence?

The development of cardiovascular disease is heavily tied to lifestyle choices. For any individual, the alteration of dietary practices, smoking cessation, the implementation of physical activity, and proper management of stress and blood pressure can greatly reduce the severity of cardiovascular disease as well reducing the risk of developing cardiovascular disease in the first place. A few specific dietary changes people can make include: the reduction of saturated fats (such as animal fats), high cholesterol foods, and refined sugars in their diet, increasing the consumption of dietary fiber (which can capture and expel cholesterol from the body), and increasing the consumption of omega 3 fatty acids which are found in foods such as fish
