Arturo was playing with a spinner that
has 5 equal areas, numbered 1, 2, 3, 4 and
5. Arturo spun the spinner 80 times and 12
of the 80 spins came up as a 5. He wanted
to see how likely a result of 12 fives in 80
spins would be with a fair spinner, so
Arturo used a computer simulation to see
the proportion of fives in 80 spins,
repeated 300 times, assuming a
probability of of spinning a 5. Create an
interval containing the middle 95% of the
data based on the data from the
simulation, to the nearest hundredth, and
state whether the observed proportion of
fives is within the margin of error of the
simulation results.
