Suppose that you have two sets of data to work with. The first set is a list of all the injuries that were seen in a clinic in a month's time. The second set contains data on the number of minutes that each patient spent in the waiting room of a doctor's office. You can make assumptions about other information or variables that are included in each data set. For each data set, propose your idea of how best to represent the key information. To organize your data would you choose to use a frequency table, a cumulative frequency table, or a relative frequency table? Why? What type of graph would you use to display the organized data from each frequency distribution? What would be shown on each of the axes for each graph? Consider how different distributions might affect the different graphs. How might other variables affect the graphs? How could graphs be made to be biased? If a graph were biased, how might you change it to guard against that bias?

8. Imagine that you have been given a large data set of mechanical measurements for the Young’s Modulus of blood vessels, as well as the amount of collagen in each sample. a.) Assuming the tissue can be well modeled as a fiber-containing two-component composite loaded longitudinally, derive a GRAPHICAL scheme for estimating the Young Modulus of collagen and elastin. b.) Sketch a graph of what your data would look like if this is a good model. Label all pertinent slopes...
You have been asked to calculate the Pearson’s correlation coefficients for the variables of a data set. The data set consists of a number of variables and a number of observations of those variables. Discuss how you might improve the computational performance of Pearson’s correlation on this data set if it consists of a) a large number of observations and a small number of variables, and b) a large number of variables and a small number of observations
Name: Continuous Random Variables: Continuous Distribution Lab Collect the Data: Use a random number generator to generate 50 values between 0 and 1 (inclusive). List them below. Round the numbers to 4 decimal places or set the calculator MODE to 4 places. Complete the table Calculate the following: 1t quartile Organize the Data Construct a histogram of the empirical data. 3rd quartile median Construct a histogram of the empirical data. Make 8 bars. Make 5 bars. Relative Frequency Relative Frequency...
Prepare: Context: What do the data mean? What is the goal of the study? Source: What is the source objective, is the source biased? Sampling: Does the method influence the validity of the conclusion? Voluntary response (self-selected?) Bias? In the previous RW0, you opened the dataset that we will use throughout the semester for all RW’s. You identified the variables and variable types. Below is a description of the data, how it was collected, and what the variables mean. Use...
Suppose you are collecting data from a country like Japan where the government sets the price of health care. Each prefecture in Japan has a different set of prices (for example, Tokyo has higher prices than rural Hokkaido). Data for 2015 is displayed in Table 1. What is the arc price elasticity of demand for health care consumers in Japan (using only this data)? Suppose that incomes are generally much higher in Tokyo than Hokkaido. Is your answer to the...
Test 1 A/B-Part 2 Show ALL. work in a neat and organized manner on separate paper. DO NOT write the answers on the test - there is not enough space. Follow directions!! ALL graphs and tables MUST either be hand-drawn or created in StatCrunch. ALL hand drawn graphs must be on Graph Paper. Label ALL graphs and tables correctly. Include your last name as part of the title on all graphs & tables. Follow specific directions for each problem. Problems...
You wish to conduct a hypothesis test to determine if a bivariate data set has a significant correlation among the two variables. That is, you wish to test the claim that there is a correlation (Ha:ρ≠0Ha:ρ≠0). You have a data set with 69 subjects, in which two variables were collected for each subject. You will conduct the test at a significance level of α=0.05α=0.05. Find the critical value for this test (Pick the closest conservative value from the table). rc.v....

Minimum Data Sets for Personal Healthcare Records Part 1 Medical facilities have implemented the use of Electronic Healthcare Records (EHRs) for a variety of reasons. Some facilities implemented their use for financial reasons while other facilities implemented their use to better serve their patient population. No matter the reason for their implementation, EHRs can be an asset to any medical facility. One problem with EHRs is that there is no standardized set of data that each EHR collects, commonly referred...
The following data sets were taken from two automated filling lines (FLO1 and FLOS). An equal number of 60 packs were randomly sampled from each flling line and the weights of the filled packs were recorded in (g) along with the frequency of each weight interval, and illustrated in the following table Weight Interval 50-799 FLO1 FLO5 800-849 850-899 900-949 14 16 950-999 20 1000-1049 10 1050 1099 100-1149 1150-1199 Use a statistical software package (e.g., Minitab, SPSS, SAS, Matlab,...
