For the last 3 years a college had 18% of their students receiving a financial aid loan miss at least one payment.  They set up a financial literacy workshop and offered it to a sample of 320 students receiving a financial aid loan.  Of the students who attended the workshop, 44 ended up missing at least one payment.  At the 5% significance level is there enough evidence to conclude that the workshop will reduce the population proportion of financial aid students who miss at least one payment?
