Using the dotplot, is there evidence that the proportion of times a spun dime lands on heads is greater than 0 point 5 ?
Answer
A
No, a proportion of 0 point 6 8 is only 0 point 1 8 more than 0 point 5 ; therefore, there is insufficient evidence that the true proportion of heads is greater than 0 point 5 .
B
No, a proportion of 0 point 6 8 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 point 5 .
C
Yes, a proportion of 0 point 6 8 proves that the true proportion of heads is greater than 0 point 5 .
D
Yes, a proportion of 0 point 6 8 only occurred once out of 100 simulated proportions; therefore, there is sufficient evidence that the true proportion of heads is greater than 0 point 5 .
