If the last packet SEQ1501 is lost, when does the sender retransmit the packet?

(1). The following table shows a trace of a TCP session. In the TCP session, a sender sends TCP packets and receives ACKs. Each packet sent contains 100-byte payload. Please figure out SampleRTT, EstimatedRT, and DevRTT when you receive each ACK. Fill the second table. We assume that the weighing factors are a-0.25 and -0.25. At the beginning, EstimatedRTT-500 ms, and DevRTT-50 ms.
