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
is the estimate
z is the zscore that has a pvalue of 
, also called the critical value.
The standard error is:
90% confidence level critical value
So 
, z is the value of Z that has a pvalue of 
, so 
.
Estimate:
72 petty theft cases and finds 45 of these have gone unsolved.
