A random sample of dogs at different animal shelters in a city shows that 13 of the 60 dogs are puppies. The city's animal shelters collectively house 1,440 dogs each year. About how many dogs in all of the city's animal shelters are puppies?
To estimate the number of puppies in all of the city's animal shelters, we can use the proportion of puppies in the random sample and apply it to the total number of dogs in the city's animal shelters.
First, let's calculate the proportion of puppies in the random sample:
Proportion of puppies = Number of puppies / Total number of dogs in the sample
Proportion of puppies = 13 / 60 = 0.2167
Next, we'll apply this proportion to the total number of dogs in all of the city's animal shelters:
Estimated number of puppies = Proportion of puppies * Total number of dogs in the city's animal shelters
Estimated number of puppies = 0.2167 * 1440
Estimated number of puppies = 312.48
Therefore, we can estimate that there are approximately 312 puppies in all of the city's animal shelters.
