An auditor needs to estimate the percentage of times
a company fails to follow an internal control procedure. A
sample of 50 from a population of 1,000 items is selected,
and in 7 instances, the internal control procedure was not
followed.
a. Construct a 90% one-sided confidence interval estimate
for the population proportion of items in which the internal control procedure was not followed.
b. If the tolerable exception rate is 0.15, what should the
auditor conclude?

Prairie, inc. produces one single product. it has an annual capacity of 10,000 units, but currently uses only 80% of it. each unit is sold for $50 and requires direct material worth $30 and direct labor worth $5. manufacturing overhead cost is $10 per unit of which 70% is variable. should a special order to sell 1,000 units at $44 be accepted? yes no

A) plot the m1 and m2 money stock in the us from 1990-2015. (hint: you may use the data tools provided by fred.) (b) plot the nominal interest rate from 1960 to 2014. (hint: you can either use the daily interest rates for selected u.s. treasury, private money market and capital market instruments from or the effective federal funds rate fromfred.) (c) the consumer price index (cpi) is a measure of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. intuitively, the cpi represents the cost of living or the average price level. plot the cpi from 1960 to 2013.(d) the inflation rate is the yearly percentage change in the average price level. in practice, we usually use the percentage change in the cpi to compute the inflation rate. plot the inflation rate from 1960 to 2013.(e) explain the difference between the ex-ante and ex-post real interest rate. use the fisher equation to compute the ex-post real interest rate. plot the nominal interest rate and the ex-post real interest rate from 1960 to 2013 in the same graph.

Afinancing project has an initial cash inflow of $42,000 and cash flows of −$15,600, −$22,200, and −$18,000 for years 1 to 3, respectively. the required rate of return is 13 percent. what is the internal rate of return? should the project be accepted?
