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 :)

Step-by-step 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

Answer:

The correct option is 3.

Step-by-step 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

$Mean=\frac{\sum fx}{\sum f}$

$Mean=\frac{0\times 2+1\times 1+2\times 3+3\times 6+4\times 2+5\times 3+6\times 2}{19}$

$Mean=\frac{60}{19}$

$Mean=3.1578$

$Mean\approx 3.2$

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