REVIEW for Exam #4 – Chapter 10, 11.1, 11.2, 11.3, 12.1, 12.2, 13.1 Problem 1 – If you’re using a graphing calculator, please write the function you’re using. Don’t forget to include the equation I gave in class. Follow the format we went over in class!! A recent study stated that if a person chewed gum, the average number of sticks of gum he or she chewed daily was 8. To test the claim, a researcher selected a random sample of 36 gum chewers and found the mean number of sticks of gum chewed per day was 9. The standard deviation of the sample was 1. At a = 0.05 , is the number of sticks of gum a person chews per day actually greater than 8? Use the Pvalue Method. a) State the hypothesis b) Find the test value c) Find the Pvalue d) Will you reject or not reject the null hypothesis? Explain how you made your decision. e) Summarize your results. Please use complete sentences. Problem 2 -If you’re using a graphing calculator, please write the function you’re using. Don’t forget to include the equation I gave in class. Follow the format we went over in class!! The Harris Poll conducted a survey in which they asked “How many tattoos do you currently have on your body?” Of the 1,205 males surveyed, 181 responded that they had at least one tattoo. Of the 1,097 females surveyed, 143 responded that they had at least one tattoo. At level of significance of 0.05, is the difference in proportions of females that have at least one tattoo different from the proportion of males that have at least one tattoo. a) State the hypotheses b) What kind of test do you have? (Right tailed-test, left tailed-test, or Two tailed-test) c) Find the test value. d) Find the P-value e) Is P-value > a or P-value=a ? f) Will you reject or NOT reject 0 H ? g) Summarize Problem 3 – If you’re using a graphing calculator, please write the function you’re using. Don’t forget to include the equation I gave in class. Follow the format we went over in class!! The average temperature during the summer months...
