Question 8 • Probability and Statistics with Applications Honors Sem-2-FL-1210300 (2024-2025)
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 are shown in the dotplot. Using the dotplot, what do the two dots above 0.70 represent?
Answer
A
There is a 2 in 100 chance that the true proportion of heads is 0.7.B
In two simulated samples of 25 spins, the proportion of heads is 0.7.C
There is a 2 in 100 chance that the sample proportion of heads is 0.7.D
In two simulated samples of 25 spins, the true proportion of heads is 0.7.
