(a) Develop a descriptive statistic that can be used to estimate the percentage of all taxpayers who file electronically. % (b) The survey reported that the most frequently used method for preparing the tax return is to hire an accountant or professional tax preparer.

a. The percentage of all taxpayers who file electronically is 58%

b. 654 people used an accountant or professional tax preparer preparing the tax return

Step-by-step explanation:

According to the given data, in order to estimate the percentage of all taxpayers who file electronically, we would have to make the following calculation:

percentage of all taxpayers who file electronically=634*100%=0.58

1,091

Hence, the percentage of all taxpayers who file electronically is 58%

In order to calculate how many people used an accountant or professional tax preparer for preparing the tax return, we would have to make the following calculation:

people used an accountant or professional tax preparer = 60%*1,091=654

100%

654 people used an accountant or professional tax preparer preparing the tax return.
