Answer: 0.8137
Step-by-step explanation:
As per given , we have

Sample size : n= 47
Let
be the sample mean o.
Then, the probability that the mean of a sample of 47 families will be between 16.6 and 17.6 pounds will be :


[∵
]

[By using p-value calculator]

Hence, the probability that the mean of a sample of 47 families will be between 16.6 and 17.6 pounds= 0.8137
First multiply 0.8 times m, then multiply 0.8 times -5.
This will give you 0.8m-4 = 10
Then add four to both sides to get you 0.8m =14.
Divide both sides by 0.8 to get m=17.5
Hope this helped. Good luck! :)
