Consider two individuals with the same income and probability of experiencing an accident that would cost them $15,000 in medical expenses. The first individual has the utility function U=ln(Y) and the second has the utility function U=ln(Y)+10. How would their willingness to pay for an insurance policy to cover all of their medical expenses differ between the two individuals?

I'm trying to work with this code that I have. i want to kick the user back if they don't enter a number in the specified range but I haven't been able to get a while loop working right.

  1. Write a program name Blackjack_Jr that allows a human user to play a single hand of "blackjack" against a dealer.
  2. Pick two values from 1-10 for the player. These are the player's "cards". These two values must be user inputs
  3. Generate two more values from 1-10 for the dealer. These two values should be randomly generated by your code
  4. Whoever has the highest total is the winner.

public class Blackjack_Jr

       int card1;

Acceptance sampling is an important quality control technique, where a batch of data is tested to determine if the proportion of units having a particular attribute exceeds a given percentage. Suppose that 8% of produced items are known to be nonconforming. Every week a batch of items is evaluated and the production machines are adjusted if the proportion of nonconforming items exceeds 10%. [You may find it useful to reference the z table.]

a. What is the probability that the production machines will be adjusted if the batch consists of 65 items? (Round “z” value to 2 decimal places, and final answer to 4 decimal places.)

Probability _________

b. What is the probability that the production machines will be adjusted if the batch consists of 77 items? (Round “z” value to 2 decimal places, and final answer to 4 decimal places.)

Create a class Person with two instance variables of type String called firstName and

LastName, an instance variable of type int called age, an instance variables of type int

called height (measured in inches), and an instance variable of type double called weight.

Define an appropriate constructor that takes initial values for all instance variables and

calls the corresponding set methods. Define get and set methods for all instance variables.

All set (mutator) methods should validate that reasonable data is being passed to the

object.

Then create a test application that queries the user for information and uses that

information to create two objects of type Person. The application should display all

information about both objects.
