Suppose diane and jack are each attempting to use a simulation to describe the sampling distribution from a population that is skewed left with mean 5

A description of the outcome would be that the only a few percent of the sample performed poorly or achieved low score, meanwhile a greater percent of the sample achieved higher scores. We can also say that some percent of the sample achieved a score lower than 5.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

the answer is 13 cm
