Answer to Problem 7.23E
0.02
Explanation of Solution
Given:
Simulation of 250 flip of a coin and assuming that heads and tails are equally likely
Formula used:
Calculation:
10 possible digits are there so assigning 5 of the digits to heads and 5 of the digits to tails
Heads: Digit 0, 1, 2, 3, 4
Tails: Digit 5, 6, 7, 8, 9
Using the TI 83 calculator for simulating the result
Generating the 250 flips of a coin using the TI83/TI84 calculator
Counting the number of heads (digits 0, 1, 2, 3, 4) in the result and repeating the simulation 100 times in total
114, 123, 114, 136, 138 ...128
It is observed that the value 140 is mentioned twice in the last 100 values.
Therefore the estimated
