Using the PERT method, calculate each task time estimate, standard

deviation, and variance. Enter your answer as a number, rounded to $2$ decimals

$(0\mathrm{.}50$ or $3\mathrm{.}67$ ; not $.5$ or $3\mathrm{.}66$ or $3\mathrm{.}6667)$ This response format requires trailing

zeroes, meaning if your answer is $2\mathrm{.}2,$ enter it as $2\mathrm{.}20.$ Using the table below, sketch out an AON Network using the average or

mean time estimates for each task, and calculate the critical path$($s$)$ using

mean task times.
