Nine experts rated two brands of Colombian coffee in a taste-testing experiment. A rating on a 7-point scale ( 1=1= 1 equals extremely unpleasing, 7=7= 7 equals extremely pleasing) is given for each of four characteristics: taste, aroma, richness, and acidity. The following data stored in Coffee contain the ratings accumulated over all four characteristics:

• a. At the 0.05 level of significance, is there evidence of a difference in the mean ratings between the two brands?

• b. What assumption is necessary about the population distribution in order to perform this test?

• c. Determine the p-value in (a) and interpret its meaning.

• d. Construct and interpret a 95% confidence interval estimate of the difference in the mean ratings between the two brands.

In applying Kolcaba's Comfort Theory, what are the "Health Care Needs" of individuals who experience opioid overdose? What are their needs of comfort and examples of "Comforting Interventions" to address their physical/ psycho-spiritual/ environmental or socio-cultural comfort needs?

Describe how personality in adulthood changes and also how it remains stable. According to Erikson, what is the major goal of adulthood? What types of experiences in adulthood would lead to that? According to the Big Five Factor of Personality, where do you think you fall on traits such as openness, conscientiousness, extroversion, agreeableness, and neuroticism? One of the major personality stereotypes in adulthood is the concept of the midlife crisis. What do researchers say about the midlife crisis?

#Problem 2

Write function write_stock that asks the user to input a company name, its associated ticker symbol (eg. Exxon, XOM), and the price per share of the stock. These are then written to file stock.txt one item per line. The user will type in ‘quit’ to stop.

Write function get_share_value that accepts a company name and the number of shares. The function will search file stock.txt and return a list of two values; the ticker symbol and the total value of the shares. This function must use an exception handler to insure the file is valid, that the price can be converted to a number, and catch any other exception that might be raised.

Write a program that calls write_stock and get_share_value. The program will ask the user for the company name and number of shares for read_stock and print the answer.

Sample output might look as follows.

Enter company name; enter quit to stop: Amazon

Enter ticker symbol: amzn

Enter price: 1000

Enter company name; enter quit to stop: Apple

Enter ticker symbol: aapl

Enter price: 125

Enter company name; enter quit to stop: Microsoft

Enter ticker symbol: msft

Enter price: 250

Enter company name; enter quit to stop: quit

What stock did you buy?: Apple

How many shares?: 10

Your total value for aapl is $1250.00

#Problem 3

Write function determine_ sums that accepts a list of values. The function will return a list of two numbers; the first is the sum of the positive numbers and the second is the sum of the negative numbers.

Write a program that defines a list as [1, 5, 7, -2, 6, -8, 10, -4, -20] and calls determine_sums. The program will print the output. Assume the company name will start with a capital letter and the ticker symbol will be all lowercase. This will give the following output.

[29, -34]

There is no user input on this problem.

#Problem 4

Write function write_students that asks the user for student records and writes them to file students.txt. A record of a student includes name, major and GPA. The user can enter as many records as they want until they type in quit.

Write function read_students that accepts a major. The function returns the highest GPA for that major.

Write a program that calls write_students and read_students and prints the major and highest GPA. The program will ask the user for the major for which to search. Assume all names and majors will be lower case.

Sample input/output might look as follows:

Enter student name; enter quit to stop: jones

Enter major: insy

Enter gpa: 2.0

Enter student name; enter quit to stop: smith

Enter major: insy

Enter gpa: 3.25

Enter student name; enter quit to stop: willis

Enter major: mana

Enter gpa: 3.25

Enter student name; enter quit to stop: quit

Enter major: insy

The highest GPA for insy majors is 3.25

#Problem 5

Write module number_functions that includes:

Function write_numbers that writes 50 random numbers between 1 and 15 to file numbers.txt.

Function read_numbers that reads the file numbers.txt and returns a list of the numbers.

Write function count_numbers that accepts the list of numbers and returns how many numbers are in the list.

Function find_even_odd that accepts the list of numbers and returns a list of two numbers; how many odd numbers are in the list and how many even numbers are in the list.

Write a program that calls these functions in the order above and prints the returned data.

Sample output might be the following. But yours may vary as we are generating random numbers. The count will always be 50, but you need to code the function as if you do not know that.

['12', '8', '3', '18', '1', '5', '3', '18', '6', '10', '20', '8', '7', '4', '17', '16', '8', '11', '14', '3', '13', '13', '5', '17', '11', '9', '16', '19', '13', '18', '6', '1', '9', '19', '5', '14', '13', '15', '10', '12', '20', '16', '14', '5', '10', '20', '17', '11', '18', '3']
