- Table 6 shows the year and the number ofpeople unemployed in a particular city for several years. Determine whether the trend appears linear. If so, and assuming the trend continues, in what year will the number of unemployed reach 5 people?Is carbon dating? Why does it work? Give an example in which carbon dating would be useful.Describe the three major categories of data (time-series, cross-sectional, and panel).
- What is moving average? What are its uses in analysis of time series? Given the numbers 2, 6, 1, 5, 3, 7, 2; write down the weighted moving average of period 3, the weights being 1, 4, 1.How do I construct a time series plot and determine type of pattern in data?Explain the different factors that account for fluctuations in time series data
