Use numbers below to help find part a variences

Activity A $-$ Time expected in days $9\mathrm{.}83$

Activity B $-$ Time expected in days $15\mathrm{.}00$

Activity C $-$ Time expected in days $7\mathrm{.}17$

Activity D $-$ Time expected in days $10\mathrm{.}17$

Activity E $-$ Time expected in days $3\mathrm{.}33$

a$)$ Calculate the$$ variance, sigma Superscript $2,$ for each activity. $($Enter your responses rounded to two decimal places.$)$

Activity A $-$ Varience $()$

Activity B $-$ Varience $()$

Activity C $-$ Varience $()$

Activity D $-$ Varience $()$

Activity E $-$ Varience $()$

Please help me fill in the $()$ and round to two decimal places. Thank You :)
