Suppose you have two individual cross-sectional data sets on car prices for the years 2002 and...
Suppose you have a circular cross sectional wire with radius R, a resistivity of ρ, and that is carrying a uniformly distributed current of I(t) = I0 cos(ωt) (notice it changes in time). a) Find the electric field that is generating this current using the proper form of Ohm’s Law. b) Find the magnetic field outside of the wire that is generated by the current and the time changing electric field combined. Question 2: Suppose you have a circular cross...
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...
If you have two data sets with the following information. Both data have a mean of 100. In Data set one: The 25th quartile 50, the 50th is 100, and the 75th is 150. Data set two: The 25th quartile 75, the 50th is 100, and the 75th is 300. Which data set is more symmetric and why do you think that?
Question 26 3 pts Suppose that you have daily closing prices each day for the month of May for Apple stock prices. This data set is best described as time-series data. survey data. cross-sectional data. panel data
What type of data is this? Select one: cross-sectional, time-series, panel data. 1)You are trying to save money for a new car and you decided to start recording your spending over time to figure out how you can do it. 2)US Government tracks health care spending as a percent of GDP over time. 3) Undergraduate student advisor keeps records of all athlete students over the course of 4 years in UIC. 4) CNN conducted a poll to find out whether...
Find some "real world" data. This data needs to have two sets of numbers that correspond to each other in an exponential pattern. Choose data with at least 10 pairs of data values. Caution: Do not select specific problems already in your text! Also, please be careful not to select exponential growth models that do not need data fitting such as doubling models. For example, if you already know a particular model grows by doubling each time period, then you...
In the picture below, I have the output for the same two sets of data. I ran the hypothesis test and the confidence interval. If you had a choice to use one output or the other, which would you choose and why? Make sure to be specific and include what information you get from each and what information you don't get if you use one over the other. Options Two sample T summary hypothesis test: : Mean of Population 1...
Big data is the collection and cross-referencing of large numbers and varieties of data sets that allows organizations to identify patterns and categories of cardholders through a multitude of attributes and variables. Every time customers use their cards, big data suggests the products that can be offered to the customers. These days many credit card users receive calls from different companies offering them new credit cards as per their needs and expenses on the existing cards. This information is gathered...
Refer to the data set (four years of ratios and graphs) in the Saputo vs Maple Leaf Foods to perform trend, cross-sectional, and integrative analysis. For the Liquidity ratio category, you should describe the overall trend of each company during the 4-year period, for example, improved, worsened, relatively stable, etc. In addition, you should present a summarized cross-sectional comparison between the two companies. An example in the profitability ratio category would be “Company A is overall more profitable than Company...
