Calculate Interest in a Java program.

If you know the balance and the annual percentage interest rate, you can compute the interest on the next monthly payment
using the following formula: interest = balance * (annualInterestRate/1200)

Write a program that reads the balance and the annual percentage interest rate and
displays the interest for the next month.

Create a scanner
Prompt the user to enter a name and create variable for scanner
Prompt the user to enter a balance and the annual percentage interest rate
Create variable double balance for scanner
Create variable double annual for interest rate for scanner

Create variable double interest which is equal to annual for interest rate divided by 1200

Display result of balance

1. Consider a bond that pays annually an 8% coupon with 20 years to maturity. The percentage change in the price of the bond if its yield to maturity increases from 5% to 7% is closest to? Set your decimal places to 4 in your financial calculator.

   a		19.50%
   b		24.22%
   c		-24.22%
   d		-19.50%

Explain why either greatly decreasing or increasing the percentage of oxygen in the atmosphere is dangerous.

Isabella gathered data on the average percentage of tips received by waitstaff in 31 restaurants in New York City. She works through the testing procedure:

• H0:μ=14%; Ha:μ≠14%
  
• α=0.1 (significance level)
  
• The test statistic is t0=x¯−μ0sn√=1.489.
  
• The critical values are ±t0.05=±1.697.
  

Conclude whether to reject or not reject H0. Select two responses below.

Select all that apply:

• Reject H0.

• Fail to reject H0.

• The test statistic falls within the rejection region.

• The test statistic is not in the rejection region.

the percentage of deaths due to disease is 12.5%. A medical student wants to test whether the percentage of deaths due to disease is less than 12.5%. She collected data on deaths due to disease over 8 states. She found out that there were 102 patients diagnosed with disease and 11 patients died. Carry out a test of significance by answering the questions below in as much detail as possible. Use a 10% level of significance. What is the value of the test statistic? (Hint: Round sample proportion to four decimal places.) Question 2 options: A) -0.53 B) 0.53 C) 0.01 D) -0.01 E) -0.05
