Expert Solution

Step 1

Note:

Hi there! Thank you for posting the question. As your question has more than 3 parts, we have solved only the first three subparts for you. If you need any specific subpart to be answered, please re-submit the question by specifying the subpart number or name.

Population:

The population of interest includes all the individuals of interest. The overall group of objects about which conclusions are to be drawn is called the population.

Step 2

Adjusted sample size:

If the sample sizes that are obtained using the formula are not accurate, then an adjustment in sample size has to be done.

The formulae for adjusted sample size are given below:

$n_{f i n a l} = n \times \frac{{(r + 1)}^{2}}{4 r}; w h e r e r = a l l o c a t i o n e r r o r n_{f i n a l} = n \times \frac{1}{1 - Q}; w h e r e Q = e x p e c t e d p r o p o r t i o n o f d r o p o u t n_{f i n a l} = n \times (1 + (m - 1) ρ); w h e r e m = s i z e o f t h e c l u s t e r a n d ρ = i n t r a c l a s s c o r r e l a t i o n n_{f i n a l} = n \times F; w h e r e F = \frac{1}{1 + \frac{n}{N}}$
