Katie thinks that people living in a rural environment have a healthier lifestyle than other people. She believes the average lifespan in the USA is 77 years and the lifespans follow an approximately normal distribution. A random sample of 13 obituaries from newspapers from rural towns in Idaho give 2-78.9 and a 2.83. Does this sample provide evidence that people living in rural Idaho communities live longer than 77 years? (a) State the null and alternative hypotheses: (Type "mu" for the symbol j, e.g. mu>1 for the mean is greater than 1, mu<1 for the mean is less than 1, mu not = 1 for the mean is not equal to 1) Hot H, (b) Find the test statistic (c) Answer the question: Does this sample provide evidence that people living in rural Idaho communities live longer than 77 years? (Use a 10% level of significance) (Type: Yes or No)
