Essay Height and Weight Data on High School Children

8. Draw conclusions – Assuming that your experiment produced results identical to those seen in Table 4, would you reject or accept the hypothesis that you produced in question 3? Explain how you determined this.

Denote by the average heights for males and females, respectively. Here are the two hypotheses:

Do you get enough exercise? Are you sure about that? Or how about this, are you overweight, do you even know? Today’s adolescents don’t. In fact today’s adolescents face serious risk from their lack of activity. Today’s children are obese because they have developed some very bad habits related to healthy living and as result can suffer serious physical and psychological damage.

The quantitative subjective data is collated and organised into forms of a line graph, table values, and the calculation of mean and median data to determine if there’s any form of deviation of data. This will prove if there’s a linear or non-linear relationship between the data and test if there’s any similarities between the data values and/or the overall skew of the graphs. The outliers will be also added onto these graphs and will be compared towards each other recognising if there is a similarity or contrast in data and in relationships between both of the data. This will determine if the hypothesis of “family size has an

Topics Distribution of the sample mean. Central Limit Theorem. Confidence intervals for a population mean. Confidence intervals for a population proportion. Sample size for a given confidence level and margin of error (proportions). Poll articles. Hypotheses tests for a mean, and differences in means (independent and paired samples). Sample size and power of a test. Type I and Type II errors. You will be given a table of normal probabilities. You may wish to be familiar with the follow formulae and their application.

2. Sort the data by Gen or Gen 1 (into males and females) and find the mean and standard deviation for each gender for the following variables: Use the descriptive stats function for one gender and the Fx functions (average and stdev) for the

Females make up the majority of the population at 26,567 compared to 24,805 for males. Based upon

c. I am very confident in making this conclusion because the data for the boys has 2 peaks, while the data for the girls has data that first increases, then decreases after the midpoint of the graph.

1. A researcher is interested in whether students who attend private high schools have higher average SAT Scores than students in the general population. A random sample of 90 students at a private high school is tested and and a mean SAT score of 1030 is obtained. The average score for public high school student is 1000 (σ= 200).

Then comparing the level of school years completed with the sex, female (N=69360) and male (N=67406), another significant relation was found t (136764) = 6.62 (0.15). The level of school years completed has a relationship with sex (see appendix F). Therefore, we reject the null hypotheses.

8. Assume that the MM207 Student Data Set is a random sample of all Kaplan students; estimate the proportion of all Kaplan students who are male using a 90% level of confidence.

Overall description of the group (demographics: education, income, location, marriage, children, etc., percentage of the population)

There was a time when chubby children were considered cute. It was assumed that their baby fat would melt away and a healthy adult would emerge. We now know that childhood obesity can be very harmful for our nations children. Not only can obesity cause health problems but also psychological problems. In observing the causes of childhood obesity, hopefully we can slow down the epidemic.

Many children are currently suffering from obesity all around the world (Zuraikat 2010). Often times if parents don’t have a good nutritional balance then their children will become obese as well. Adults might not care what others think of them, but most likely their children will be bullied in school. There is a lot of discrimination around the world till this day towards obese people (Zuraikat 2010). Believe it or not if two people go apply for the same job position often times the one that looks physically better will get the job. For this reason, it is significantly important to maintain a well-balanced nutritional diet starting at a young age. There are times when children are consuming high portions of fat

Biostatistics is important to study as undergraduates delve deeper into their studies of Biology and learn how the study of life is integrated into more than just their college-level science courses. Looking into the use of statistics at a scientific level at this stage of our education is preparing determined and enthusiastic students for the world of medicine as one day we will have to read and analyze sets of data and more than likely give the statistics of our patients’ issues. Biostatistics is allowing students to explore the world of medicine using a different approach, mathematically and critically. The purpose of this experiment was to determine if a significant multiple regression exists between my 3 quantitative variables, Weight, Height and Age and to determine the best regression model to use when making predictions.
