- 2) A researcher is interested in studying if male smokers and female smokers smoke a different number of cigarettes each day. She takes a sample of 10 male smokers and 10 female smokers from a nearby motorcycle club by asking the first 10 smokers of each gender she encountered. Their results are recorded below. Male 18 25 30 16 24 32 15 27 19 15 Female 12 15 36 30 12 18 34 22 10 12 Answer the following: a. Create appropriate graph(s) that can be used to compare the samples. Using the graph(s) to explain: does it appear that the number of cigarettes smoked by each gender are different? b. To run a formal test, which test will you run and which distribution will you use? Explain why for each. Are there any concerns you have about using the results of this test? c. Write the following hypothesis in symbols: Null Hypothesis: The average number of cigarettes smoked by male and female smokers is the same.
