Answer:

3.6669

Step-by-step explanation:

Given is a frequency distribution and we are expected to find the mean of the distribution.

Let X be the no of total pets owned and f be the number of adults owning those pets.

                                                          Total

x   1    2    3           4          5                   6                 7    

F 248 567 1402 728         419                 456                203     4023

x*f 248 1134 4206 2912 2095        2736         1421     14752

       

Mean        3.666915237

Thus we find the total of all frequencies and then sum of product of x*f.

Mean = sum of f*x/sum of x

Here mean= 3.6669
