Note: Submit all answers rounded to at least 4 decimal places. The 1-VAR STATS function on your graphing calculator will be useful for thi exercise. 1. Calculate the mean and standard deviation of increase in percent COHb resulting from smoking a cigarette. xincrease=Sincrease= 2. Calculate the mean percent COHb both before and after smoking. xbefore=xafter= 3. Is the mean increase in percent COHb from part 1 equal to the difference in the means of the before and after measurements? That is to say, is xafterxbefore=xincrease ? 4. Calculate the standard deviation of percent COHb both before and after smoking. Sbefore=
