- The Truth in Lending Act Many lending agencies compound interest more often than yearly, and, as we noted in Example P.2, they are required to report the annual percentage rate, or APR, in a prominent place on the loan agreement. Furthermore, they are required to calculate the APR in a specific way. If r is the monthly interest rate, then APR is calculated using APR=12r. a. Suppose a credit card company charges a monthly interest rate of 1.9%. What APR must the company report? b. The phrase annual percentage rate leads some people to believe that if you barrow 6000 from a credit card company that quotes an APR of 22.8%, and if no payments are made, then at the end of 1 year, the interest would be calculated as 22.8% simple interest on 6000. How much would you owe at the end of a year if interest is calculated in this way? c. If Interest is calculated monthly which is common, then the actual amount you would owe in the situation of part b is given by 60001.01912. What is the actual amount you would owe at the end of a year?In 2014, the median salary nationwide for a high school teacher was $56,310 per year. The median annual wage for all workers was $35,540.SOURCE: United States. Department of Labor. "High School Teachers." Occupational Outlook Handbook. 17 Dec. 2015. Web. 7 March 2016. Suppose a worker makes $29,000 in wages per year. Find the percent increase in salary the worker can expect if he/she trains to be a teacher and can expect to earn a salary of $40,000. Enter your response to the nearest 0.1% %You may need to use the appropriate appendix table or technology to answer this question. Individuals filing federal income tax returns prior to March 31 received an average refund of $1,059. 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) 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. Develop appropriate hypotheses such that rejection of H0 will support the researcher's contention. A) H0: ?= $1,059 Ha: ? ≠ $1,059 B) H0: ?< $1,059 Ha: ?≥ $1,059 C) H0: ? ≥ $1,059 Ha: ? < $1,059 D) H0: ?> $1,059 Ha: ? ≤ $1,059 E) H0: ?≤ $1,059 Ha: ? > $1,059 (b) 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 ? = $1,600may be…
