Question

The Dunking Principle

Mr. Crow, the principal at Arizona State University agreed to participate in a dunking booth during the homecoming fair. Here’s how the booth worked:

People who purchased tickets would push a button. The button operated a light above the booth, and the light was programmed to flash either green or red using a randomizing mechanism. If the light turned green, Mr. Crow was dunked, but if it turned red he stayed dry. He was told the light was set to have a 50% chance of turning green.

As it turned out, Mr. Crow seemed to be getting dunked far more than 50% of the time. In fact, after 20 pushes of the button, he had been dunked 15 times! He was pretty suspicious of what he had gotten himself into.

3. Suppose the fair continued and Mr. Crow was dunked 46 times out of 60 pushes of the button. Would that convince you that the dunking booth was not set the way he had been told? What about 72 dunks out of 100 pushes?

4. Mr. Crow’s experience – 15 dunks out of 20 pushes of the button – represented 75% dunks. Question 3 asked about other examples involving approximately 75% dunks. If you were not convinced by either result described in Question 3 that the booth was not set at 50% green, how many occurrences of about 75% dunks would it take to convince you of that? IF you were convinced by the results described in Question 3, what is the smallest 75% dunk result that would convince you. In either case, explain your answer.

I don't need help with 3, just only need help with 4

Answer 1

@jhonyy9

Answer 2

so you dont need help with first 3 - what ybout 4th ?

Answer 3

about 4th

Answer 4

just only 4, i need help

Answer 5

what not is cleraly from there ?

Answer 6

This question is a bit oddly worded. But I think if you had 100 trials and roughly 75 or so resulted in a dunk, then I'd say its more than enough info to suggest things are skewed against Mr Crow. I'm not sure the exact number needed. I cant really find info about that.

Answer 7

15 dunks out of 20 pushes of the button mean 75% mathematicaly or not ?

Answer 8

yeah i think

Answer 9

so than you just need answering this last part of : IF you were convinced by the results described in Question 3, what is the smallest 75% dunk result that would convince you. In either case, explain your answer.

Answer 10

bill 50% may mean or yes or not - true ?

Answer 11

55% may be more yes that no by 5% so this may convince you ?

Answer 12

i think so

Answer 13

you need deciding how you think what percent of this may convince you about this that that the booth was not set at 50% green

Answer 14

it would have to be at least 5 or 6 times of it being 75% dunks

Answer 15

my opinion that this 75% is to much to convince me about this booth was yes set at 50% green

Answer 16

15 dunks out of 20 pushes of the button mean 75% so this you say convince you about this - right ?

what about 11 dunks out of 20 pusches of the button ? this may convince you too ?

Answer 17

probably because this is more than 50% on yes - but i dont know what may be your opinion ?

Answer 18

so hope you understand it now better - bye bye i need to go
