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. ..ياااس 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.
