I am having trouble setting up these problems. While answers are welcome, I am interested in figuring out how to read the word problem and plug in the information to arrive at the answer. Please look at the attached document.

3. A medical researcher wishes to see whether the pulse rates of smokers are higher than the pulse rates of nonsmokers. Samples of 100 smokers and 100 nonsmokers are selected. The results are shown here. Can the researcher conclude, at a = 0.05, that smokers have higher pulse rates than nonsmokers? Solve using the traditional method. Smokers: X,= 85 $12 = 27 n1 = 100 Nonsmokers: X2= 82 $22 = 38 n2 = 100 4. The Tennis Industry Association reported that 41% of tennis fans were female. If, in a sample of 30 tennis fans, 14 were female, do the results suggest that the percentage may have changed? Use a = 0.02. Solve using the Traditional Method. p= 15/30 = 0.47 n = 30 Test the Null hypothesis that p = 0.41
