without outlier
mean = (2+8+5+6+20+7)/6
mean= 48/6
mean= 8
with outlier
mean=(4+2+8+5+6+20+7+9)/8
mean=61/8
mean=7.63
without outlier
median=11/2=5.5
with outlier
median=11/2=5.5

Numbers of Tomato plants to be reported in 30 minutes = 5 unit
Step-by-step explanation:
It is given that ,
Time taken to report 20 Tomato plants (P1) = 120 minutes (T1)
