1. So I have a hypothetical data: data d1; input country$ year avgtemp; datalines; GBR 2001 60 GBR 2002 61 ... USA 2016 72 USA 2017 73 ; run; I) what proc step would allow me to see the change in temperature of GBR over different years? II) what proc step would allow me to see USA and GBR temperature changes over the years? III) How do I produce the 5point statistic(box plot) of the temperatures for GBR and USA IV) what significant outcome can be taken from the statistical output reported by SAS on this data from the previous answers? 2. I have two pairs of recorded numbers data d2; input x1 x2; datalines; .. .. ; run; I) in a proc step, determine or exclude possible statistical connections (simple) II) which are the important SAS reporting numbers to support your conclusion above? III) we later learn that the x2 variable is a log(log(x2)) process, produce a new variable x3 which will remove the log effects and analyze x1 against x3, do your conclusions change? 3. We have a dataset of animal populations: data d3; input $species population; datalines; snakeRed 1000 snakeBlue 1200 ... birdRed 2000 birdBlue 2300 ; run; I) choose a manner to visualize the distribution of the birds and snakes as groups II) choose a manner to visualize the bird populations III) use proc sql to subset the data and calculate the 10% increase in population for the blue snake
