Question

Central Eye Clinic advertises that 90% of its patients approved for LASIK surgery to correct vision problems have successful surgeries.
Use the random digit assignment model of part (a) to simulate the outcomes of 15 trials. Begin at column 1, line 2. (Enter S for success and F for failure, separated by commas.)

Your friend assigned the digits 1 through 9 to the event "successful surgery" and the digit 0 to the event "unsuccessful surgery." Does this assignment of digits simulate 90% successful outcomes? I Answered yes. then the next part:

Using this digit assignment, repeat part (b). (Enter S for success and F for failure, separated by commas.)

Answer 1

Lasik is dangerous

Answer 2

How is this related to math?

Answer 3

I apologize, I didn't paste the question correctly. It's a statistics question.

Answer 4

Oh my apologies i did not see the bottom part i only saw the top part earlier thank you for adding the second part

Answer 5

whats the random digit assignment model?

Answer 6

it says begin at column 2

Answer 7

I guess you can say, if a digit is between 0 and 4, then it is success, if it is between 5 and 9 , it is failure

Answer 8

so go down the column, tell me what numbers you get

Answer 9

when you reach the end of the column, go back up to the next column from the top

Answer 12

I'm sorry for some reason I can't stay connected. That website is the "random number table"

Answer 13

ok I see it

Answer 14

can you also upload the original question

Answer 15

sure. Let me get that ready

Answer 16

Central Eye Clinic advertises that 90% of its patients approved for LASIK surgery to correct vision problems have successful surgeries.

(a) In the random number table, assign the digits 0 through 8 to the event "successful surgery" and the digit 9 to the event "unsuccessful surgery." Does this assignment of digits simulate 90% successful outcomes? **answered yes

(b) Use the random digit assignment model of part (a) to simulate the outcomes of 15 trials. Begin at column 1, line 2. (Enter S for success and F for failure, separated by commas.)

(c) Your friend assigned the digits 1 through 9 to the event "successful surgery" and the digit 0 to the event "unsuccessful surgery." Does this assignment of digits simulate 90% successful outcomes? **also answered yes

Using this digit assignment, repeat part (b). (Enter S for success and F for failure, separated by commas.)

Answer 17

so in your random digit table, what did you get for part a)

Answer 18

I get 9,7,5,3,0 ..

Answer 19

I'm just not understanding the whole table thing. To me it just seems so random. Why would just guessing be so exact?

Answer 20

the random number table has equal probability for every number 0-9 . but you are biasing your results by saying S = numbers 0 -8

Answer 21

the random number table is more random than guessing, because humans dont guess randomly (according to studies). the random number table is made with a random number generating function

Answer 22

ok so write down the random numbers you got

Answer 23

okay. So when they mention assign digits 0 thru 8, for example; the first number is 92630. Or do I read those numbers separately, 9 2 6 3 0?

Answer 24

you read those seperately, but the directions say to start at column 1 line 2

Answer 25

right, thank you. so it's 7 9 4 4 5. Now what determines success or failure?

Answer 26

a number 0 through 8 is success, 9 is failure

Answer 27

so you have
S F S S S

Answer 28

oh!! Okay! I get it. so using the same theory with the next set of numbers, just as an example.
7 8 7 3 5. Would be S S S S S

Answer 29

correct

Answer 30

Awesome! Thank you So much! Appreciate your help.
