Chapter 7, Problem 11CRP

For Problems 4–19, categorize each problem according to the parameter being estimated: proportion p, mean m, difference of means μ1μ2, or difference of proportions p1p2. Then solve the problem.

Archaeology: Pottery Three-circle, red-on-white is one distinctive pattern painted on ceramic vessels of the Anasazi period found at the Wind Mountain archaeological site (see source for Problem 7). At one excavation, a sample of 167 potsherds indicated that 68 were of the three-circle, redfion-white pattern.

  1. (a) Find a point estimate p ^ for the proportion of all ceramic potsherds at this site that are of the three-circle, red-on-white pattern.
  2. (b) Compute a 95% confidence interval for the population proportion p of all ceramic potsherds with this distinctive pattern found at the site.

Most people know that the probability of getting a head when you flip a fair coin is . You want to use the relative frequency of the event to show that the probability is . How many times should you simulate flipping the coin in the experiment? Would it be better to use 300 trials or 3000 trials? Explain.
