(please give me the answer)​

Answer 1

Answer:

Step-by-step explanation:

Numbers Frequency

1                    1

2                    2

3                    1

4                    3

5                    5

6                    4  

7                    2

8                    1

9                    1

(i) 9 is the highest number.

(ii) 1 is the lowest number

(iii) Range of the data = Highest number - Lowest number

9-1=8

(iv) Arithmetic mean = \frac{sum\ of\ observations}{number\ of\ observation}

= \frac{(1\times1) + (2\times2) + (3\times1)+ (4\times3 )+ (5\times5 )+ (6\times4) + (7\times2)+(8\times1)+(9\times1)}{20}

\\ = \frac{1 +4 +3 +12+ 25+ 24 +14 +8 +9}{20} \\\\ = \frac{100}{20} \\\\ = 5

Therefore, mean of the data is 5
