    Question

    The probability that the coin is fair (pure) is considered. It is assumed that the coin is fair and it is assumed that the probability of coin (or head) is 0.5. 50 tosses are made and with this number of tosses it is assumed that the central limit theorem can be used can be used. It is found that 31 times coin comes out on top of the 50 throws, a proportion of 31/50 = 0.62. The researchers want to know the probability of this proportion 0.62 or greater. That probability is


    1. TRUE: 0.045
    2. FALSE: 0.095
    3. FALSE: 0.125

    1. 0.045: Correct
