Question

HEEELLLPPPP PLLLLSSS Linda asked the students of her class their hockey scores and recorded the scores in the table shown below:

Score. Number of students
0 2
1 1
2 3
3 6
4 2
5 3
6 2
Based on the table, what is the mean hockey score?
2.7
2.9
3.2
5.2

Answer 1

Answer: My best guess? 3.2 Good luck :)

Explanation:

The mean is the amount of numbers aka 7 and the total of the numbers added together, 21. Divide to get 3 and you can order the number of students to 1, 2, 2, 2, 3, 3, 6. Outlier 6 so I was leaning towards 5.2 but if you look at the data next to each other Score 3, # of Students 6. SO I evidently got 3.2. Hope this helps.

Answer 2

The correct option is 3.

Explanation:

The given table is

Score(x). Number of students(f)

0 2

1 1

2 3

3 6

4 2

5 3

6 2

The formula for mean is

`Mean=(\sum fx)/(\sum f)`

`Mean=(0* 2+1* 1+2* 3+3* 6+4* 2+5* 3+6* 2)/(19)`

`Mean=(60)/(19)`

`Mean=3.1578`

`Mean\approx 3.2`

The mean hockey score is 3.2, therefore the correct option is 3.
