4. Last year the Consumer Price Index (CPI) indicated that inflation was 3%. Assuming new cars increased by the rate of inflation, how much did a $30,000 car increase in price? 5. If housing prices fall by 4%, how much will the value of a $200,000 home decline in price this year?

6. If job growth in the state of Utah is projected to be 2% and there are 11 million workers in the state, how many new jobs will be created this year?

7. Jordan’s raise at work last year was 3% of her salary, but inflation numbers released by the CPI indicate that inflation was 3% last year. How much did Jordan’s purchase power change?
Explain your answer.

8. Bill learned that he could make an additional $2,000 annually if he was fluent in Spanish. If he intends to learn Spanish and work another 10 years, how much is learning Spanish worth to him?

Overproduction of uric acid in the body can be an indication of cell breakdown. this may be an advance indication of illness such as gout, leukemia, or lymphoma.† over a period of months, an adult male patient has taken nine blood tests for uric acid. the mean concentration was x = 5.35 mg/dl. the distribution of uric acid in healthy adult males can be assumed to be normal, with σ = 1.87 mg/dl. (a) find a 95% confidence interval for the population mean concentration of uric acid in this patient's blood. what is the margin of error? (round your answers to two decimal places.) lower limit upper limit margin of error (b) what conditions are necessary for your calculations? (select all that apply.) σ is unknown n is large σ is known normal distribution of uric acid uniform distribution of uric acid (c) interpret your results in the context of this problem. there is not enough information to make an interpretation. the probability that this interval contains the true average uric acid level for this patient is 0.05. the probability that this interval contains the true average uric acid level for this patient is 0.95. there is a 95% chance that the confidence interval is one of the intervals containing the population average uric acid level for this patient. there is a 5% chance that the confidence interval is one of the intervals containing the population average uric acid level for this patient. (d) find the sample size necessary for a 95% confidence level with maximal margin of error e = 1.10 for the mean concentration of uric acid in this patient's blood. (round your answer up to the nearest whole number.) blood tests
