Given : Sample size : n= 33
Critical value for significance level of 
: 
Sample mean : 
Standard deviation : 
We assume that this is a normal distribution.
Margin of error : 
i.e. 
Hence, the margin of error is
Answer:

Each pair of pants cost $27. Set up a system of equations.
5t + 5p = 220
5t + p = 112
Subtracting the second equation from the first,
4p = 108
p =27
