Math & Music (Raw Data, Software Required):
There is a lot of interest in the relationship between studying music and studying math. We will look at some sample data that investigates this relationship. Below are the Math SAT scores from 8 students who studied music through high school and 11 students who did not. Test the claim that students who study music in high school have a higher average Math SAT score than those who do not. Test this claim at the 0.05 significance level.

You should be able copy and paste the data directly into your software program.

(a) The claim is that the difference in population means is positive (μ₁ − μ₂ > 0). What type of test is this?

This is a two-tailed test.

This is a right-tailed test.    

This is a left-tailed test.

(b) Use software to calculate the test statistic. Do not 'pool' the variance. This means you do not assume equal variances.
Round your answer to 2 decimal places.

t = ?

(c) Use software to get the P-value of the test statistic. Round to 4 decimal places.
P-value = ?

(d) What is the conclusion regarding the null hypothesis?

reject H₀

fail to reject H₀    

(e) Choose the appropriate concluding statement.

The data supports the claim that students who study music in high school have a higher average Math SAT score than those who do not.

There is not enough data to support the claim that students who study music in high school have a higher average Math SAT score than those who do not.    

We reject the claim that students who study music in high school have a higher average Math SAT score than those who do not.

We have proven that students who study music in high school have a higher average Math SAT score than those who do not.

Consider a 30-year mortgage for $345,552 at an annual interest rate of 5.6%. After 13 years, the mortgage is refinanced to an annual interest rate of 3.5%. How much interest is paid on this mortgage?

The wavelength of the four Balmer series lines for hydrogen are found to be 410.1, 434.3, 486.6, and 655.9 nm. What average percentage difference is found between these wavelength numbers and those predicted by 1 λ = R 1 nf2 − 1 ni2 ? It is amazing how well a simple formula (disconnected originally from theory) could duplicate this phenomenon.

According to Kantian moral theory, is it permissible to lie to someone as long as the lie benefits the person lied to? For instance, would a doctor be permitted to lie to her patient if she was certain the lie would benefit the patient in some way?

a) Yes. The consequence of the action is the most important element, so if the patient benefited from a lie, then the ultimate outcome was good and it was right to lie.

b) No. Kant believed that lying violated a person's autonomy and was therefore always wrong.

c) Kant argued that while lying was manipulative, it was not inherently right or wrong.

d) Kant believed that lying was situational and could be either right or wrong, depending on the outcome.

Suppose that Coca-Cola is considering a new capital budgeting project. The project will use debt with maturities of 15 years. To determine the cost of debt for the project, an analyst at Coca-Cola looks at currently trading Coca-Cola debt. The analyst is looking at a Coke bond that trades today for $984.00. This bond has an annual coupon rate of 8.00%, face value of $1,000, and will mature in 15 years. The marginal tax rate for Coca-Cola is 38.00%.

What is the after-tax cost of debt for Coca-Cola?

First City Bank pays 6 percent simple interest on its savings account balances, whereas Second City Bank pays 6 percent interest compounded annually. If you made a $69,000 deposit in each bank, how much more money would you earn from your Second City Bank account at the end of 10 years? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) Difference in accounts $

When Parvati Patil took over as the new department manager, she discovered that the existing staff was unusually inefficient and unproductive. Parvati learned that the previous manager often criticized and chided staff members for every little mistake until many of the best employees had left and the rest felt demoralized.

Parvati resolved not to criticize or punish staff members unless it was absolutely necessary. Instead, she frequently complimented them whenever they did a good job. She set daily production goals for them, and every Friday afternoon she bought lunch for all staff members who met their goals each day that week. Moreover, Parvati randomly conducted spot checks on what staff members were doing; if she found them hard at work, she gave them small rewards such as extra break time.

Within just three months, productivity in Parvati’s department nearly doubled. It became the most efficient department in the company.

1). How did Parvati take advantage of principles of operant conditioning to modify her staff’s behavior?

2). How could Parvati train her staff to complete a complex new task that they had never done before? Be sure to specifically name and describe the technique that she would be using

3). How might Parvati make use of principles of cognitive learning theory to improve her staff’s productivity?

4). Name and describe 2 types of partial reinforcement schedules Parvati used

Define a class for the student record. The class should instance variables for Quizzes, Midterm, Final and total score for the course and final letter grade.

The class should have input and output methods. The input method should not ask for the final numeric grade, nor should it ask for final letter grade. The classes should have methods to compute the overall numeric grade and the final letter grade. These two methods will be void methods that set the appropriate instance variables.

Make sure to add default constructor.

Your program should use all the described methods. You should have set of Accessor(getter) and mutator(setter) methods for all instance variables, whether your program uses them or not.

The program should read in the students’ scores two quizzes, midterm and final and display the student’s records, which consists of all the above +final number and final letter grade.

Overall numeric grade is calculated as 50%-final exam, 25%-midterm and two quizzes together count for 25%.

For letter grade

90-100 is A

80-89 is B

70-79 is C

60-69 is D

And any grade <60 is F grade

When taking input, quiz grades are out of 10 points and midterm and final are out of 100 points.

please explain how from birth boys and girls are often treated differently, first in how they are dressed, parent-child interactions and the toys they are provided. Although historically treating boys and girls differently may have been helpful in directing them towards their traditional roles, considering many women are now becoming single mothers and both men and women are desiring a larger choice in jobs, not necessarily the gender stereotypical jobs, can you please discuss how this childhood socialization may not be helpful in the new direction we are trying to head in. What can be done to encourage more equality in the genders and do we want it? Please explain.

There’s a fairly new product for retirement mutual funds that target your date of retirement. I’m not sold on the product. I’m 59 years old. Over the last 10 years the Vanguard Index500 fund averaged a 10.49% annual return. The 2025 (retirement target date 6 years from now) retirement fund has averaged a 5.13% over the last 10 years. At age 49 I had $200,000 in retirement funds and for the next 17 years (to age 66) $12,000 per year is invested in the fund. (Assume all monies are invested at the beginning of the year.) Now we don’t know what future returns will be but let’s speculate they both will perform identically to past history. At age 66 (7 years from now) how much will I have in the Index500 fund? How much would I have in the 2025 target fund if I listened to an investment “expert” when I was 49 years old and invested in the retirement target fund? In dollars, how much was the financial mistake investing in the 2025 target fund?

Consider a 20-year mortgage for $359,670 at an annual interest rate of 4.8%. After 9 years, the mortgage is refinanced to an annual interest rate of 2.1%. What are the monthly payments after refinancing?
