Jerry indicated that after tossing a penny 30 times, the relative frequency of heads was 0.47 (to the nearest hundredth). He ind
icated that after 31 times, the relative frequency of heads was 0.55. Are Jerry’s summaries correct? Why or why not?
1 answer:
Answer:
Incorrect.
Step-by-step explanation:
1 toss could not change the frequency by such a large margin 0.47 ---> 0.55.
The number of heads obtained in 30 tosses = 30 * 0.47 = 14.
So if the next toss came up heads the relative frequency of heads would be
15/31 = 0.48.
