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 What is the wording of the parameter in the context of this problem?

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
