Matt thinks that he has a special relationship with the number 6. In particular, Matt thinks that he would roll a 6 with a fair 6-sided die more often than you'd expect by chance alone. Suppose ?p is the true proportion of the time Matt will roll a 6. (a) State the null and alternative hypotheses for testing Matt's claim. (Type the symbol "p" for the population proportion, whichever symbols you need of "<", ">", "=", "not =" and express...

She believes the average lifespan in the USA is 77 years. A random sample of 15 obituaries from newspapers from rural towns in Idaho give i = 80.47 and s = 1. Does this sample provide evidence that people living in rural Idaho communities live longer than 77 years? (a) State the null...
