- 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.

| 1 | 2 | 3 | 4 | 5 | 6 | 7 |
---|---|---|---|---|---|---|---|

| 248 | 567 | 1402 | 728 | 419 | 456 | 203 |

What is the estimated mean for the population? Explain your answer and show your work.

Answer: **526.9**

**The formula to find the estimated mean for the population based on the data will be: Mean= (Σ f(x)) / (Σ f)**

**x is going to be the Total of Pets Owned, while f is going to be the Number of Adults.**

**By plugging in the data into this formula you get:**

**((1*248)+(2*567)+(3*1402)+(4*728)+(5*419)+(6*456)+(7*203)) / (1+2+3+4+5+6+7)**

**Simplify and reduce**

**14752/28 = 526.857**

**Round up: 526.9 **

Thank You SO Freaking Much!!!
