2. a pet food company wants to know the number of pets owned by adults ages 21 to 70. the frequency table shows the data from a simple random sample of the targeted population. total pets owned 1 2 3 4 5 6 7 number of adults 248 567 1402 728 419 456 203 what is the estimated mean for the population? explain your answer and show your work.

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    

F2485671402728         419                 456                203     4023

x*f2481134420629122095        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
