Tossing a thumbtack. If you toss a thumbtack on a hard surface, what is the probability that it will land point up? Estimate this probability p by tossing a thumbtack 100 times. The 100 tosses are an SRS of size 100 from the population of all tosses. The proportion of these 100 tosses that land point up is the sample proportion ^p. Use the result of your tosses to give a 95% confidence interval for p.Write a brief explanation of your findings for someone who knows no statistics but wonders how often a thumbtack will land point up.
