1. A state’s Division of Motor Vehicles (DMV) claims that 60% of all teens pass their driving test on the
first attempt. An investigative reporter examines an SRS of the DMV records for 125 teens; 56 of them
passed the test on their first try. Is there convincing evidence at the α=0.01 significance level that the
DMV’s claim is lower?

2. In a recent year, 65% of first-year college students responding to a national survey identified “being
very well-off financially” as an important personal goal. A state university finds that 102 of an SRS of
200 of its first-year students say that this goal is important. Is there convincing evidence at
the α=0.05 significance level that the proportion of all first-year students at this university who think
being very well-off is important differs from the national value of 65%?

3. Every road has one at some point—construction zones that have much lower speed limits. To see if
drivers obey these lower speed limits, a police officer uses a radar gun to measure the speed (in miles
per hour, or mph) of a random sample of 10 drivers in a 25 mph construction zone. Here are the data:
27 33 32 21 30 30 29 25 27 34
Is there convincing evidence at the α=0.01 significance level that the average speed of drivers in this
construction zone is greater than the posted speed limit?

4. A school librarian purchases a novel for her library. The publisher claims that the book is written at a fifth-grade reading level, but the librarian suspects that the reading level is lower than that. The librarian selects a random sample of 45 pages and uses a standard readability test to assess the reading level of each page. The mean reading level of these pages is 4.8 with a standard deviation of 0.6. Do these data give convincing evidence at the α=0.01 significance level that the average reading level of this novel is less than 5?

In February 2012, the Australian Accounting Standards Boards decided at its meeting to propose the withdrawal of AASB 1031 Materiality. There were several reasons for this proposal which includes: there is no International Reporting Standard equivalent and it does not look like there will be, since 2005 there has been the gradual withdrawal of additional Australian guidance from a number of Australian Accounting Standards, and there is now an updated guidance on materiality in the IASB Conceptual Framework. The major impact of the withdrawal of AASB 1031 is the removal of the specific quantitative guidance for materiality. The withdrawal of AASB 1031 became effective to annual reporting beginning on or after 1 July 2015. REQUIRED: 1. Summarize the significant changes with AASB 1031 Materiality (issued by the Australian Accounting Standards Boards - AASB) from 1995 to 2015.

OPEN SKY

Mr. Jean-C. Lapierre and Mr. Jim Peterson, respectively Minister of Transport and Minister

for International Trade, announced today that the governments of 410 Part Four Businesses

and markets Canada and the United States have reached a transport agreement said to be

"open-air", which widens the scope of the agreement from 1995 and has promising

benefits. So, Canadian passenger and air cargo carriers will have better access to the large

American market, from where they may reach destinations in other countries; the pricing

rules will be relaxed for carriers Canadian and American; Canadian airports will have more

freedom to adopt measures to attract American carriers and offer better prices to

consumers.

"Certainly further liberalization of the Canada-US air transportation relationship will allow

the airlines of both countries to better meet the needs of travelers and freight forwarders,"

said Mr. Lapierre, "I am confident that "This agreement will help create new markets and

new services, lower prices and stimulate competition."

For Peterson, "the movement of people, goods and between Canada and the United States

plays a role crucial to the smooth running of our daily activities [...] The flexibility adopted

here, which goes far beyond eyes of 1995, will improve the functioning of NAFTA and

make North America more competitive. "

Transports Canada, 11 novembre 2005

A Roman numeral represents an integer using letters. Examples are XVII to represent 17, MCMLIII for 1953, and MMMCCCIII for 3303. By contrast, ordinary numbers such as 17 or 1953 are called Arabic numerals. The following table shows the Arabic equivalent of all the single-letter Roman numerals:
M 1000 X 10
D 500 V 5
C 100 I 1
L 50
When letters are strung together, the values of the letters are just added up, with the following exception. When a letter of smaller value is followed by a letter of larger value, the smaller value is subtracted from the larger value. For example, IV represents 5 - 1, or 4. And MCMXCV is interpreted as M + CM + XC + V, or 1000 + (1000 - 100) + (100 - 10) + 5, which is 1995. In standard Roman numerals, no more than three consecutive copies of the same letter are used. Following these rules, every number between 1 and 3999 can be represented as a Roman numeral made up of the following one- and two-letter combinations:
M 1000 X 10
CM 900 IX 9
D 500 V 5
CD 400 IV 4
C 100 I 1
XC 90
L 50
XL 40
Write a Python code with a class to represent Roman numerals. The class should have two constructors. One named “toArabic” constructs a Roman numeral from a string like "XVII" to “seventeen” or "MCMXCV" to “one thousand nine hundred ninety-five”. It should throw an exception if the string is not a legal Roman numeral. The other constructor named “toInt” constructs a Roman numeral to an integer such as "XVII" to “17” or "MCMXCV" to “1995”. It should throw an exception if the integer result is outside the range 1 to 3999.
