Draw boxplots (by hand is the easiest) of the data for each year
For the particular Year 2 that you chose, what is the maximum growth rate a country could have and still have a lower growth rate than 75% of the other countries in the world? Explain.
Out of the years you chose, in which year did the smallest growth rate in GDP occur? What is the value and how did you determine it?
Based on your summary statistics, did “Year 1” have higher GDP growth rates than the other two years? Give reasons for your answer. Make sure to not just compare max and min values, but rather use all the values of the 5-number summary and/or a boxplot. You might also argue based on the shape of the distribution and discuss the impact of outliers in your analysis.
Which of the years you chose has the largest variability? Explain
a)Given the data 63, 64, 66, 67, 67, 69, 71, 72 are the units of actual sales of TV in the last eight periods. Find the forecast for the ninth period using simple exponential smoothing.Use α = 0.3 and initial forecast using simple average of last eight months.
b)The sales of a company (in million dollars) for each year are shown in the table below. Find the linear sales trend line.x (year) 2005 2006 2007 2008 2009y (sales) 12 19 29 37 45

A histogram is a graph that organizes quantitative data, like counts and measurements, so we can see the distribution of these data values (i.e. how they vary). The horizontal axis shows the range of values we might see in the data. The vertical axis shows the frequency, or how many times those values appear in our data set. Number of subjects (Note: The axes on graphs in statistics rarely include "break lines" when the graphs do not start at 0. Likewise, the location of 0 is sometimes offset, i.e. moved over, to help us better read the graph.) The following histogram shows the results of a study of adolescent girls in Pennsylvania.
