Point estimate for the difference between two population proportions is the difference between the two sample proportions, written as:
and the standard deviation is given by
When np and n(1-p) is greater than 5, then the sampling distribution is approximately normal and we can use standard normal methods.
Thus, the propability of a test <span>for the difference between two population proportions is given by

Step-by-step explanation: Often times, this number will be rounded to the nearest hundreth to be .15
In the context of data models, relationships among records in a hierarchical model are called Branches. This is further explained below.
<h3>What
are data models,?</h3>
Generally, The act of generating a visual representation of either a whole information system or portions of it in order to express the linkages between different data points and structures is known as data modeling.
In conclusion, When discussing data models, the connections between different records in a hierarchical structure are referred to as "Branches."

Answer:
C
Step-by-step explanation:
Growth can be represented by the equation 
. We know that r=2% or 0.02 in this situation so we have 1.02. We know t=100 hours and the starting population A=200. We substitute these values and use a calculator to evaluate.
We now use our calculator to evaluate the exponent first and then multiply by 200.
