Tim is a wildlife biologist studying deer parasites. During a study, he finds that 12 out of 32 deer were affected by parasites. How many of the 1200 deer in the local population would he expect to be affected by parasites?

Respuesta :

It is expected that 450 out of the total 1,200 are to be affected by parasites

Here, using a study of sample, we want to infer the number of casualty in a larger sample

To do this, we need to get the percentage of the Deers that are affected by parasites

We can have this as;

[tex]\frac{12}{32}\text{ }\times\text{ 100 = 37.5\%}[/tex]

From the above, we can see that 37.5% is affected

So, to get the number affected on the larger scale, we have that;

[tex]\frac{37.5}{100}\text{ }\times\text{ 1200 = 450}[/tex]
