Critical Thinking: Simulation 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?

(b) Use the random-digit assignment model of part

(a) to simulate the outcomes of 15 trials. Begin at column 1, line 2.

(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? Using this digit assignment, repeat part (b).
