Step-by-step 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
