... 3.3.a- Assuming that the given mean and standard deviation have not changed, find the probability of randomly selecting 40 cigarettes with a mean of 0.882 g or less. 3.3.b- Based on the result from part (a), is it valid to claim that the amount of nicotine is lower (Is it a rare event)? Why or why n ...
