  • My answer would be, that for the second graders, the best time would be in between 20-25. Why? It's simple, from kindergarten up until the third grade, the amount of testing is rising, peaking at third grade. After that we can see a slow decline, each next grade, we have less and less testing. I hope that helped
  • Answer:

    The BEST prediction for the number of days testing, for 2nd grade is:

                                                 25

    Step-by-step explanation:

    From the bar graph we observe that the grades first increases and then decreases and hence, the bar graph is symmetric about the 3 rd grade.

    Also, the value to the left are slightly higher then those on the right.

    and hence the number of days would be slightly higher than 25.

            Hence, the value will be close to 25.
