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 $2\mathrm{.}20.$ What is the revised project duration using the task estimated times. Enter

your answer as a number, rounded to $2$ decimals $(0\mathrm{.}50$ or $3\mathrm{.}67$ ; not $\mathrm{.}5$ or $3\mathrm{.}66$ or

$3\mathrm{.}6667).$ What is the standard deviation of the revised project duration using the

task estimated times. Enter your answer as a number, rounded to $2$ decimals

$(0\mathrm{.}50$ or $3\mathrm{.}67$ ; not $\mathrm{.}5$ or $3\mathrm{.}66$ or $3\mathrm{.}6667).$What is the likelihood that the project will be completed in $20$ days or less?

Enter your answer as a percentage, rounded to $2$ decimals $(12\mathrm{.}34$; not $0\mathrm{.}1234).$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.
