Question
100%

Hello could you plz explain to me the parts I have blank. Much appreciated 

According to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23%
of all complaints in 2007 were for identity theft ('Consumer fraud and, 2008). Assume a state had 362
complaints of identity theft out of 1470 consumer complaints . Calculate a 93% confidence interval for the
proportion of all complaints that are complaints of identity theft in that state.
P: Parameter
What is the correct parameter symbol for this problem?
p V
What is the wording of the parameter in the context of this problem?
The percentage of all consumer complaints in that state that are for identity theft
A: Assumptions
●
Since qualitative
Vinformation was collected from each object, what conditions do we need
to check? Check all that apply.
Onp≥ 10
✔N > 20n
On 30 or normal population.
On(1-p) ≥ 10
n(1-p) 10
o is unknown.
✓n(p) > 10
o is known.
Check those assumptions:
1. np= 362
2. n(1-P)=
3. N= 1000000
which is 2 V 10
which is 2 V
which is > V
10
If no N is given in the problem, use 1000000
N: Name the procedure
The conditions are met to use a 1-Proportion Z-Interval V
