Answer 2

Answer:

The mean of the above provide information is 6.5

Step-by-step explanation:

Given:

N = 30

$f_i x_i$ = 195

We need to calculate the mean from the given information

We know that Mean = $\frac{\sum f_ix_i}{\sum f_i}$

where f is the frequency

We can also write the above formula as $\frac{\sum f_ix_i}{N}$

=> Mean = $\frac{\sum f_ix_i}{N}$

              = $\frac{195}{30}$

               = 6.5

Therefore, mean of the above provide information is 6.5
