Two students made worldwide headlines by spinning a Belgian euro 250 times

More conclusions. In January 2002, two students made worldwide headlines by spinning a Belgian euro 250 times and getting 140 heads—that’s 56%. That makes the 90% confidence interval (51%, 61%). What does this mean? Are these conclusions correct? Explain.

a) Between 51% and 61% of all euros are unfair.

b) We are 90% sure that in this experiment this euro landed heads on between 51% and 61% of the spins.

c) We are 90% sure that spun euros will land heads between 51% and 61% of the time.

d) If you spin a euro many times, you can be 90% sure of getting between 51% and 61% heads.

e) 90% of all spun euros will land heads between 51% and 61% of the time.
