The standard deviation for CO levels in moderate smokers is (use 3 significant figures):

We want to sort the data based on the number of cigarettes smoked per day. Group 1: Heavy smokers: those who smoke more than 30 cigarettes/day (>30) Group 2: Moderate smokers: those who smoke between 10-30 cigarettes/day (10-30) Group 3: Light smokers (those who smoke less than 10 cigarettes (

Report the mode of the number of cigarettes smoked per day. Report your answer with 2 significant figures

By looking at the histogram, do you think the data is: Hint: Sometimes it’s useful to look at measures of central tendency to make this decision

What is the probability that carbon monoxide levels in moderate smokers will be between 75- 300? Report your answer using 2 significant figures.

The mean CO level for light smokers is (use 3 significant figures):
