Explanation:

Your question isn't complete but here is it.

a. Develop a descriptive statistics that can be used to estimate the percentage of all taxpayers who file electronically.

This will be:

= 649/1052 × 100%

= 61.69%

b. The survey reported that the most frequently used method for preparing the tax return is to hire an accountant. If 60% of the people have their tax return prepared this way, how many people used an accountant?

This will be:

= 60% × 1052

= 60/100 × 1052

= 0.6 × 1052

= 631.2

= 631 people
