Question 1127296: 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.
You can put this solution on YOUR website! The mean is the number of pets * number of adults
all divided by the total number of adults
1*248=248
2*567=1134
3*1402=4206
4*728=2912
5*419=2095
6*456=2736
7*203=1421
Number of adults=4023
pets*adults sum is 14752
divide 14752/4023=3.67 pets per adult is the mean or expected value.
