Develop and interpret a life table, given data.

One thousand two hundred and five (1,205) persons, who were accidentally exposed to a large-dose gamma-radiation leak on December 1, 2019, were followed for a year and their mortality experience was recorded monthly (as at month-end). Some were lost to follow-up during this time period and the whereabouts and outcome of these persons is unknown. The table below lists the monthly-recorded deaths and "withdrawals".

Please draw a survival curve for these data (using the cumulative survival for each month).
