2 6
3 5
4 6
5 □
6 5

8 4
9 4
10 3

Answer 1

4

Explanation:

The nine given values add to 5+6+5+6+5+8+4+4+3=46, so the missing frequency is 50−46=4.

Answer 2

4

Explanation:

Add up all the frequencies given

5+6+5+6+5+8+4+4+3 = 46

The total frequencies with the missing data value should add up to 50

50 = 46 + x

x = 50 - 46

x = 4
