A survey of 250 homeless persons showed that 14 were veterans. Find a point estimate for the population proportion of homeless p
1 answer:
Answer:
And for this case that represent the 5.6% of the homeless persons who are veterans
Step-by-step explanation:
We know that in a survey of 250 homeless persons 14 were veterans. We can find the estimated proportion of homeless persons who are veterans with the following formula:
The last one is an unbiased estimator of the true population proportion p
And replacing the info given we got:
And for this case that represent the 5.6% of the homeless persons who are veterans

In the first octant, we assume
, so we can ignore the caveats above. Now,
so that the only critical point in the region of interest is (1, 2, 2), for which we get a maximum value of
.
We also need to check the boundary of the region, i.e. the intersection of
with the three coordinate axes. But in each case, we would end up setting at least one of the variables to 0, which would force 
, so the point we found is the only extremum.
