34. Smoking. A research paper19 described two common types of smokers: (a) Morning Highs: those who tend to smoke more in the morning than the rest of the day, and (b) Flatlines: those who tend to smoke at the same rate all day. A sample of 43 smokers from the Morning High group had a mean of 30.7 cigarettes smoked per day, with a sample standard deviation of 10.5 cigarettes. A sample of 247 smokers from the Flatline group had a mean of 22.0 cigarettes smoked per day, with a sample standard deviation of 7.7 cigarettes. Test whether the population standard deviation of the Morning High group is greater than that of the Flatline group, using . Assume that the samples are independent and that the two populations are normally distributed.
