Let n be the total total random deaths involved in study. Let x be the number of deaths caused by accidents.
Here we have to find the point estimate for true percentage of all deaths that are caused by accidents.
The point estimate for true percentage is sample proportion.
So here the sample proportion of number of deaths caused by accidents is point estimate.
It is obtained as
Sample proportion p =
= 25 / 615
Sample proportion p = 0.04
The best point estimate for the true percentage of all deaths that are caused by accidents is 0.04
