Question
A student decides to spin a dime and determine the proportion of times it lands on heads. The student spins the
dime 25 times and records that it lands on heads 17 times. Let p = the true proportion of times the dime would land
on heads when spun. Under the assumption that the true proportion is 0.5, 100 simulated proportions for samples of
size 25 is shown in the dotplot.

Simulated proportions of samples, n 25
Using the dotplot, is there evidence that the proportion of times a.spun dime lands on heads is greater than 0,5?
O Yes, a proportion of 0.68 proves that the true proportion of heads is greater than 0.5.
O Yes, a proportion of 0.68 only occurred once out of 100 simulated proportions; therefore, there is sufficient
evidence that the true proportion of heads is greater than 0.5.
O No, a proportion of 0.68 is only 0.18 more than 0.5; therefore, there is insufficient evidence that the true proportion
of heads is greater than 0.5.
O No, a proportion of 0.68 or more occurred 7 times out of 100 simulated proportions; therefore, there is insufficient
evidence that the true proportion of heads is greater than 0.5.
