Question: An issue of The Wall Street Journal reported an increase in the percentage of taxpayers who used professional preparers from 45% in 1986 to 47% in 1987. A study was conducted in 1988 to see if a significant increase in the usage of professional prepares occurred. A random sample of 1000 taxpayers was surveyed, and 494 indicated they used a professional preparer. Using the 0.1 significance level, can it be concluded that there has been an increase since 1987?
