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
Answer:
I'm gonna have to say 54%.
Step-by-step explanation:
It says right in the question, "At a breakfast buffet, 54% of people choose coffee for their beverage"
Answer:
y = -(x - 2)^2.
Step-by-step explanation:
Vertex form is a(x - b)^2 + c where a is a constant and (b, c) is the vertex.
Here b = 2 and c = 0
So we have:
y = a( x - 2)^2 + 0
When x = 4 y = -4 so:
-4 = a( 4 - 2)^2
a = -4/2^2 = -1
So the required equation is
y = -(x - 2)^2.
