The national center of education statistics conducted a survey of high school seniors, collecting test data on reading, writing, and several other subjects. here we examine a simple random sample of 200 students from this survey. side-by-side box plots of reading and writing scores as well as a histogram of the differences in scores are shown below

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

how many players are there?
