Question
We used technology to simulate selecting 100 SRSS of size
n = 50 from a population of pennies in which 13.2% are
pre-1982 copper pennies. The dotplot shows p = the sample
proportion of copper pennies for each of the 100 samples.
4. There is one dot on the graph at 0.22 (or 22%). Explain
what this dot represents.
5.0%
10.0% 15.0% 20.0% 25.0%
Simulated sample percent of Copper Pennies
30.0%
5. Assuming that 13.2% of pennies in circulation are pre-1982 copper pennies, is it surprising to randomly
select 50 pennies for which p = 11/50 = 22% or greater? Justify your answer.
6. Based on your previous answers, is there convincing evidence that more than 13.2% of pennies in Jenna's
container are pre-1982 copper pennies? Explain your reasoning.
