Thirty-two small communities in Connecticut (population near 10,000 each) gave an average of x = 138.5 reported cases of larceny per year. Assume that σ is known to be 42.5 cases per year.

(a) Find a 90% confidence interval for the population mean annual number of reported larceny cases in such communities. What is the margin of error? (Round your answers to one decimal place.)

(b) Find a 95% confidence interval for the population mean annual number of reported larceny cases in such communities. What is the margin of error? (Round your answers to one decimal place.)

(c) Find a 99% confidence interval for the population mean annual number of reported larceny cases in such communities. What is the margin of error? (Round your answers to one decimal place.)

(d) Compare the margins of error for parts (a) through (c). As the confidence levels increase, do the margins of error increase?

As the confidence level increases, the margin of error increases.As the confidence level increases, the margin of error decreases.    As the confidence level increases, the margin of error remains the same.

(e) Compare the lengths of the confidence intervals for parts (a) through (c). As the confidence levels increase, do the confidence intervals increase in length?

As the confidence level increases, the confidence interval decreases in length.As the confidence level increases, the confidence interval remains the same length.    As the confidence level increases, the confidence interval increases in length.

Question 3 A study of workers earning minimum wage were grouped into various categories, which can be interpreted as events when a worker is selected at random. Considering the following events: E: worker is under 20 years of age F: worker is white G: worker is female Describe the following events in words • E’ • F ꓵ G’ • E ꓴ G Question 4 if a single card is drawn from an ordinary deck of cards, find the probability it will be a red or a face card. (Face cards are Jack, Queen, and King) Question 5 Supposed two fair die are rolled. Find the probability the first die shows a two or the sum of the result is six or seven. Question 6 If two fair die are rolled find the probability that the sum of the numbers rolled is greater than three. (Be careful of the phrase greater than). please show work or give explnation so i can try and figure out how to do the problems

Create an abstract class Employee. Your Employee class should include the following attributes:

First name (string)

Last name (string)

Employee id (string)

Employee home street address (string)

Employee home city (string)

Employee home state (string)

Write a constructor to initialize the above Employee attributes. Create an abstract method called earnings. Create another class HourlyEmployee that inherits from the abstract Employee class. HourEmployee must use the inherited parent class variables and add in attributes HourlyRate and HoursWorked. Your HourEmployee class should contain a constructor that calls the constructor from the Employee class to initialize the common instance variables but also initializes the HourlyRate and HoursWorked. Implement the Employee abstract earnings method in HourlyEmployee to calculate the earnings for a week. Note that earnings is hourly rate * hours worked.

Create a test class that prompts the user for the information for two hourly employees, creates the 2 two hourly employees objects, calls the earnings method then displays the attributes and earnings for each of the two hourly.

Ann O'Rexia suffers from anorexia nervosa. In addition to a low body weight, decreased muscle mass, glycogen, and fat stores, she has iron deficiency anemia. She constantly feels weak and tired. When she walks, she feels pain in her calf muscles. On this visit to her nutritionist, they discuss the vitamin content of her diet and its role in energy metabolism.  She is deficient in thiamine, riboflavin, biotin and niacin (the vitamin precursor of NAD+). In the context of the metabolic pathways discussed in Chapter 14, specifically how would these affect carbohydrate metabolism.

Chapter 20, programming challenge 2: Linked List Sorting and Reversing

Modify the LinkedList1 class presented in this chapter by adding sort() and reverse() methods. The reverse method reverses the order of the elements in the list, and the sort method rearranges the elements in the list so they are sorted in alphabetical order. Do not use recursion to implement either of these operations. Extend the graphical interface in the LinkedListDemo class to support sort and reverse commands, and use it to test the new methods.

Question 12 PYTHON:

Write a function named first_last that takes a single parameter, string_list (a list of strings). The
function first_last should return a list of the strings in string_list that are not empty and that begin
and end with the same letter.

For example, the following would be correct input and output for the function first_last.

response = ['to', 'that', 'I', 'say', '', 'hurrah']
print(first_last(response))
['that', 'I', 'hurrah']

Question 13 (20 points)

Write a function named number_luck. The function number_luck takes two parameters:

1. lucky, a list of lucky numbers between 2 and 12, inclusive
2. unlucky, a list of unlucky numbers between 2 and 12, inclusive

Every number is either lucky, unlucky or boring (neither lucky nor unlucky).

The function number_luck should

1. ask the user for a number in the range 2 to 12 (you may assume that the user provides valid
input)
2. print a message echoing the user’s number and stating whether it is lucky, unlucky or boring
3. return an integer that is the user’s number

For example, the following would be correct input and output.

>>> a_num = number_luck([7, 11], [2, 3, 12])
Give me a number from 2 to 12: 7
7 is lucky. You win!
>>> print(a_num)
