Q
Random Condition
A
makes sure that phat is a valid point estimate
2
Q
Large Counts condition
A
Allows us to use a Normal Distribution to calculate z*
np>_10
n(1-p)>_10
3
Q
10% condition
A
Allows us to sample with replacement
n<0.10N
4
Q
State
A
% CI for p = true proportion of (context)
5
Q
Plan
A
One/two-sample z interval for p
Check conditions
6
Q
Do
A
p-hat +_ z* square root of p-hat(1-p-hat)/n
7
Q
Conclude
A
We are %C that the interval () captures p, the true proportion of (context)
