(15 points) The bit stream 1110 0111 1010 is transmitted using the standard CRC algorithm described in the book. The generator polynomial is r + x + x + 1. Show the actual bit string transmitted. Suppose that the THIRTEENTH (13th) bit from the left in the transmitted message is inverted during transmission. Show that this error is detected on the receiver's end. Show every step in your calculations for full credit.
