(1 point) It is estimated that approximately 8.1% of Americans are afflicted with diabetes. Suppose that a certain diagnostic evaluation for diabetes correctly diagnoses 95% of all adults over 40 with diabetes as having the disease and incorrectly diagnoses 3.5% of all adults over 40 without diabetes as having the disease.

Use this information and a theoretical group of 10,000 Americans to construct a table for this testing scenario. Round all answers and results to four decimal places.

What percentage of Americans who test positive for diabetes would we expect to actually have the disease?  %

What percentage of Americans who test negative for diabetes would we expect to actually have the disease?  %

What percentage of Americans who test positive will not have the disease?  %

Suppose that people consume only three goods, as shown in this table:

Complete the following table by computing the percentage change in price for each of the three goods.

Using a method similar to that used to calculate the consumer price index, the percentage change in the overall price level is.

True or False: If you were to learn that a bottle of Gatorade increased in size from 2017 to 2018, that information would raise your estimation of the inflation rate.

True

False

True or False: If you were to learn that Gatorade introduced new flavors in 2018, that would imply that the inflation rate you estimated is understated.

QUESTION 6

1. Consider an economy where banks keep 25% of deposits as reserves. Currency is 50 billion pesos, which constitutes 10% of the monetary base.

   
       (a) Calculate the monetary base.
       (b) Calculate the money supply.
       (c) If the central bank requires a reserve-deposit ratio of at least 10%, calculate banks' excess reserves.
       (d) If the currency-deposit ratio increases by 3 percentage points, calculate the resulting money supply assuming that the monetary base and the reserve-deposit ratio stay the same.
       (e) In answering this question, assume that the change in the currency-deposit ratio described in (d) never happened. If the central bank buys 10 billion pesos worth of securities, calculate the percentage change in the monetary base and the percentage change in the money supply assuming that the currency-deposit ratio and the reserve-deposit ratio stay unchanged.

1) Which of the following analytical procedures would not provide information on a potential misstatement( either understatement or overstatement) of the allowance for uncollectible accounts?

a- compare allowance for uncollectible accounts as a percentage of accounts receivable with previous years

b- compare aging categories as a percentage of accounts receivable with previous years

c- compare current year gross margin percentage with previous year gross margin

d- compare number of days accounts receivable are outstanding with previous years

2) An appropriate response to finding significant exceptions in tests of controls is as follows:

a- decrease reliance on controls and adjust substantive test accordingly

b- Increase tolerable misstatement( and overall materiality) for relevant accounts in the cycle where the controls were found lacking

c- None of the other responses is correct

d- decrease your reliance on substantive testing of accounts in the cycle where the controls were found lacking

Suppose that LMN stock currently is selling at $48 per share. You buy 400 shares using $14,000 of your own money, borrowing the remainder of the purchase price from your broker. The rate on the margin loan is 5%.

a. What is the percentage increase in the net worth of your brokerage account if the price of LMN immediately changes to: (i) $51.36; (ii) $48; (iii) $44.64? What is the relationship between your percentage return and the percentage change in the price of LMN? (Leave no cells blank - be certain to enter "0" wherever required. Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.)

b. If the maintenance margin is 25%, how low can LMN's price fall before you get a margin call? (Round your answer to 2 decimal places.)

The manager of the Burrard Credit Union wishes to know if there is a significant difference
between male and female customers’ interest in a proposed new type of savings certificate. A
survey of 200 randomly selected customers has yielded the following data:

INTEREST

SEX Strong Moderate Weak Total
Male 30 25 25 80
Female 60 40 20 120
Total 90 65 45 200

(a) What percentage of customers shows a strong or moderate interest in these savings
certificates? [2 marks]

ANSWER

(b) What percentage of customers is male AND shows a strong or moderate interest in
these savings certificates? [2 marks]

ANSWER

(c) What percentage of male customers do NOT show a strong interest in these savings
certificates? [2 marks]

ANSWER

(d) Among those customers who show a weak interest in these types of savings certificates,
what is the probability that they are a female?

(ii) The market consists of the following stocks. Their prices and number of shares are as follows: Stock Price Number of Shares Outstanding A $10 100,000 B 20 10,000 C 30 200,000 D 40 50,000 (a) What is the percentage increase in the market if a S&P 500 type of measure of the market (value-weighted average) is used? b. The price of Stock C doubles to $60. What is the percentage increase in the market if a S&P 500 type of measure of the market (value-weighted average) is used? c. Repeat question (b) but use a Value Line type of measure of the market (i.e., a geometric average) to determine the percentage increase. d. Suppose the price of stock B doubled instead of stock C. How would the market have fared using the aggregate measures employed in (b) and (c)? Why are your answers different?
