Question

Mr. Clark claims that he has a coin that is weighted so that the probability of heads is 40%. To test this, his students flip the coin 200 times and calculate the relative frequency of heads and tails.
Outcome Heads Tails
Relative frequency 0.38 0.62
Select from the drop-down menus to correctly complete each statement.
The relative frequency of heads is
A.reasonably close to
B.very different from
40%.
Mr. Clark's claim about the theoretical probability is likely to be
A.true
B.false

This means that the theoretical probability of tails is most likely
A.0.50
B.0.60
C.0.70

Answer 1

1. The relative frequency of heads is (A) reasonably close to 40%.
2. Mr. Clark's claim about the theoretical probability is likely to be (A) True.
3. This means that the theoretical probability of tails is most likely 0.6 for this coin.

Answer 2

Answer:

A) Option A

B) Option A

C) Option B

Step-by-step explanation:

A) Outcome of relative frequency was that the frequency of getting heads was 0.38 or 38% which is reasonably close to 40%.

B) This clears that the theoretical probability claimed by Mr. Clark was likely to be true

C) This means the theoretical probability of tails is most likely to be = 1 - 0.40 = 0.60 or 60% Therefore option B. is correct.
