A random telephone survey of 1021 adults (aged 18 and older) was conducted by Opinion Research Corporation on behalf of CompleteTax, an online tax preparation and e-filing service. The survey results showed that 684 of those surveyed planned to file their taxes electronically (CompleteTax Tax Prep Survey 2010).
- 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. If 60% of the people surveyed had their tax return prepared this way. how many people used an accountant or professional tax preparer?
- c. Other methods that the person filing the return often used include manual preparation. use of an online tax service, and use of a software tax program. Would the data for the method for preparing the tax return be considered categorical or quantitative?

randomly selected Americans aged 18 or older stated that they believed that NAFTA was bad for the United
States.
a. Find the point estimate for the proportion of Americans who believe that NAFTA was bad for the
United States. Round your answer to 4 decimal places.
b. Find the margin of error for a 95% confidence interval. Round your answer to 4 decimal places.
c. Construct the 95% confidence interval for the proportion of Americans who believe that NAFTA was
bad for the United States. Enter your answer as an open interval of the form (a,b) and round to 3
decimal places.
d. Can you conclude that more than half of Americans believe that NAFTA was bad for the United
States?

Individuals filing federal income tax returns prior to March 31 received an average refund of $1,057. Consider the population of "last-minute" filers who mail their tax return during the last five days of the income tax period (typically April 10 to April 15). For a sample of 400 individuals who filed a tax return between April 10 and 15, the sample mean refund was $910. Based on prior experience, a population standard deviation of σ = $1,600 may be assumed. What is the test statistic? (Round your answer to two decimal places.) What is the p-value? (Round your answer to four decimal places.) p-value = Find the value of the test statistic. (Round your answer to two decimal places.) State the critical values for the rejection rule. (Use ? = 0.05. Round your answer to two decimal places. If the test is one-tailed, enter NONE for the unused tail.) test statistic≤test statistic≥arrow_forwardA federal auditor for nationally chartered banks, from a random sample of 100 accounts, found that the average demand deposit balance at the First National Bank of Arkansas was $549.82. If the auditor needed a point estimate for the population mean for all accounts at this bank, what should he use? There's no acceptable value available. The average of $549.82 for this sample. The auditor should survey the total of all accounts and determine the mean. The average of $54.98 for this sample.arrow_forward
- 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.arrow_forwardThe North American Free Trade Agreement (NAFTA) enacted in 1994 is a trilateral trade agreement signed by the United States, Canada and Mexico.

Consider the population of “last-minute” filers who mail their tax return during the last five days of the income tax period (typically April 10 to April 15). A researcher suggests that a reason individuals wait until the last five days is that on average these individuals receive lower refunds than do early filers. For a sample of 400 individuals who filed a tax return between April 10 and 15, the sample mean refund was $910. Based on prior experience, a population standard deviation of σ = $1,600 may be assumed. Test the researcher's assertion using the critical value approach.
