Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
For this problem, we have that:
90% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The lower bound for a 90% confidence interval for the percentage of all American adults who believe in ghosts is 0.3549

Hello!
The variable "n" represents an exponent.
An exponent is used to multiply a number (b) by itself "n" times. For example, if the expression were to read (b²) it would represent the following:
b × b
The same could be said for (b³):
b × b × b
Even (
):
b × b × b × b × b × b × b × b × b × b
I hope this helps!
