Determine whether the situation calls for service in observational study or experiment. You want to find out if years of lifting heavy weights has an affect on flexibility.

answer: l

step-by-step explanation:

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

the solution is h=10 because you add 9 to each side of the equation.

unless if u could do my questions, if not i wouldn't want to
