Doug is going to ride his bicycle 3,000 miles across the united states, from coast-to-coast. he wants to choose the route that will give him the greatest chance of success. here's what he finds in his research:

-there have been 2 attempts on the northern route from maine to washington. both of those riders made it 2,000 miles and quit in montana.

-there have been 19 attempts on the central route from virginia to california; 9 of those riders didn't make it out of virginia and the other 10 made it all the way to the pacific.

-there have been 32 attempts on the southern route from florida to san diego. one of those riders made it the whole way. another one went half a mile, realized he was out of shape, and quit. the other 30 riders quit somewhere in texas. they were evenly distributed between 1,300 and 1,700 miles.

which of the following is true? choose all answers that apply.

-the southern route has the lowest median distance traveled among the three routes.

-the standard deviation for distance traveled on the northern route is very low.

-the interquartile range for distance traveled on the southern route is less than 500 miles.

-the standard deviation for distance traveled on the southern route is less than the standard deviation for distance traveled on the central route.
