phi · Answer

any idea what "distribution"  this is ?

nurali · Answer

no.

phi · Answer

If it's a normal distribution,  50%  drive < 6.2

phi · Answer

Select all that are correct.

if more than 45% correct than the others are also

phi · Answer

It is reasonable to think  more than 50% drive less than 15.5 miles
so you can expect  more than 41 workers drive less than 15.5 miles

but more than 25 is correct.  (41>25)
same logic for the other choices.
