Java application of a circle

Write a Java application to calculate the circumference and the area of a circle. Your application must have two classes. The Circle class will have two methods: the circumference method and the area method. Each method will take a double input parameter as the value of the radius, perform its calculation, and return a double result.

The CircleTest class will have a main method that uses a JOptionPane to get the value of the radius from the user. The main method will create an object of the Circle class and test its methods. The main method will also use a JOptionPane for output. Use Math.PI and the Math.pow method in your calculations.

Limit your output to three digits after the decimal point by using the String.format method. Add exception handling to your program so that, if the user inputs something other than a string of digits, your program catches the exception and gives the user another chance to input the value of the radius.

1. Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Identify the null and alternative hypotheses, test statistic, p-value, critical value(s), and state the final conclusion that addresses the original claim.
– In a manual on how to have a number one song, it is stated that a song must be no longer to of 227.6 seconds and a standard deviation of 55.36 seconds. Use a 0.05 significance level and the accompanying minitab display to test the claim that the sample is from a population of songs with a mean greater than 210 seconds. What do these results suggest about the advice given in the manual?
Minitab display
One-sample T
Test of mu=210 vs >210
N=40
Mean = 227.60
St dev= 55.36
Se mean= 8.75
95% lower bound = 212.85
T= 2.01
P=0.026

2. A simple random sample of 59 adults is obtained from a normally distributed population, and each persons red blood cell count ( in cells per microliter) is measured. This sample mean is 5.25 and the sample standard deviation is 0.53. Use a 0.01 significance level and given calculator display to test the claim that the sample is from a population with a mean less than 5.4, which is a value often used for the upper limit of the range of normal values. What do the results suggest about the sample group?
t-test
u< 5.4
t= -2.173909174
p= 0.0169032278
x= 5.25
Sx= 0.53
N= 59
a. Identify the null and alternative hypotheses
b. Identify the statistic that is relevant to the test (type interger or decimal)
c. Identify the test statistic (round 3 decimal places)
d. Identify the p value (round 4 decimal places)
e. Find the critical values (left tailed,right or double)(round 3 decimal places)

3. For the following claim, find the null and alternative hypotheses, test statistic, p-value, critical value, and draw a conclusion. Assume that a simple random sample has been selected from a normally distributed population.
Claim: the mean IQ score of statistics professors is greater than 129.
Sample data: n=16
X=130
S=12
Significance level is a = 0.05
