@mebs

Answer 16

is option E right?

Answer 17

In a histogram the curve is not continuous... It must add up to 1 because that is the requirement of a normal curve...And of course all the values are positive because there are not negative decimals to add up to 1..

Answer 18

what? yea, negative decimals CAN add up to one

Answer 19

be careful... data values and probabilities are different things. data values can be negative, probabilities cannot.

It doesn't have to be far or close to the mean. I would say A could be a potential answer...
