Apet 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

Thank you for posting your question here. I think the question is "
What is the estimated mean for the population? Explain your answer and show your work."

Below is the solution. I hope it helps.

µ= (1*248 +2*567 +3*1402 +4*728 +5*419 +6*456 +7*203)/(1 +2 +3 +4 +5 +6 +7) 
=14752/28≈ 526.9
