The Family and Medical Leave Act provides job protection and unpaid time off for full time employees in the U.S. from work for a serious illness or birth of a child. In 2000, 60% of the respondents of a survey stated that it was easy to get time off for these circumstances. A researcher wishes to see if the percentage who said it was easy to get time off has changed. A sample of 100 people who used the leave showed that 53% found it easy to get the leave.
