Problem 3 In communications, the estimate of bit error rate (BER) is calculated as the ratio p = %, where Ne is the number of bits received in error and N is the total number of bits transmitted. The "true\" bit error rate is expected to be P9 = 10\". Use the Chebyshev inequality to determine how many hits you have to transmit so that the BER estimate does not differ from the \"true\" value by not more than 50%, with 90% confidence
