1. We want to test to see whether average SAT scores for science majors equals the average SAT scores for non-science majors. We collect the following sample SAT scores:

Science            Non-Science

440                  1000

1550                1010

1400                970

370                  1020

600                  980

800                  1000

1390                1080

1100   

1500   

1480   

450     

1430   

Use Excel to test this hypothesis at the 0.05 level by first testing variances (at the 0.05 level) and then means. Submit your Excel file along with your explanation.

Identify the appropriate statistical test for each research description:

1. Single-sample z-test

2. Single-samplet-test

3. Independent samples t-test

4. Related samples t-test (repeated measures or matched samples)

5. Correlation

A researcher investigates whether single people who own pets are generally happier than singles without pets. A group of non-pet owners is compared to pet owners using a mood inventory. The pet owners are matched one to one with the non-pet owners for income, number of close friendships, and general health.

You are in charge of pricing tickets for an upcoming event at the outdoor amphitheater where all seating is by general admission(no assigned seats). Demand for the event can be segmented into students and non-students. Student demand is Qst=10,000-100P. Non- student demand can be expressed as Qns=5000-10P. Your marginal cost per attendee is $10 and is constant. The capacity of the amphitheater is 5000. Since you can check for a student ID, you can charge each group a different price. What price do you charge each group?

Given the following sequence: LHYEAIAKAWNDAF

a. Classify each amino acid into polar, non-polar, & charged (at pH 7.0)–put a letter above each to show if polar (p), non-polar (n), or charged (c).

b.What are the ionizable groups?

c.What is the order of the pKaʼs going from low to high pH

d.What is the isoelectric point (pl) of this peptide?

e.At the pHʼs of 3, 6, & 9, what is the charge state?

f.What type of secondary structure would this peptide take and why?

g.How long would it be?

h.How many hydrogen bonds, at maximum

1. Complete an NCLEX style question. Provide the rationales for your answer. The question should be a multiple-choice style question.
2. Provide one question from each area (therapeutic and non-therapeutic concepts).

Therapeutic: Providing information, Clarifying, Focusing, Paraphrasing, Validation, Asking relevant questions,

Summarizing, Self-disclosure, Confrontation, Active listening, Using silence

Non-Therapeutic: Asking personal questions, Giving personal opinions, Changing the subject, Automatic responses, False reassurance,

Asking for explanations, Approval, or disapproval, Defensive responses, Passive or aggressive responces

Here are two sets of BNF grammars specifying the syntax of a language:

<exp> ::= <term> | <term> + <exp> | <term> - <exp>

<term> ::= <op> | <op> * <term>

<op> ::= <int> | <id> | (<exp>)

*********************************************

<exp> ::= <term> | <term> + <exp> | <term> - <exp> | (<exp>)

<term> ::= <op> | <op> * <term>

<op> ::= <int> | <id>

<int> will lead to non-terminals of a digit or digit sequence '123' etc.

<id> will lead to non-terminals of letters 'ABC' etc.

Do these grammars have the same set of possible outputs?

Are these grammars syntactically different? Are they semantically different? Explain

1. Determine if each of the following recursive definition is a valid recursive definition of a function f from a set of non-negative integers. If f is well defined, find a formula for f(n) where n is non-negative and prove that your formula is valid.

   1. f(0) = 1, f(n) = -f(n-1) + 1 for n ≥ 1

   2. f(0) = 0, f(1) = 1, f(n) = 2f(n-1) +1 for n ≥ 1

   3. f(0) =0, f(n) = 2f(n-1) + 2 for n ≥ 1

Mr Howe a junior partner of CPA fir, Dewey, CHeatem and Howe (DCH) is very excited about the opprtunities created by fair value relvaluation of non current assets. hr believes that there is an enormous opportunities for large firms to increase their book profits via the gains from such revaluations.

Required:

Mr Tu Dewie has asked you to review the AASB rules on the fair market revaluation of non current assets and to assess what profit enhancing opportunities may arise because of those rules.
