E. D. Hirsch, in his book Cultural Literacy, has developed a list of things that all American students should know to be "culturally literate." Review Hirsch's book to determine the criteria for inclusion and exclusion on this (www.goodreads.com/book/show/76884 (Links to an external site.)Links to an external site.). What person(s) or group(s) should have the authority to create such a mandate?  

Write a simple java program to list roman numeral for a given range of numbers.

Roman numerals are represented by seven different symbols: I, V, X, L, C, D, and M.

I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1000

Roman numerals are usually written largest to smallest from left to right. But a number

like 4 is not written as IIII. It is written as IV.

Because the one is before the five, we subtract it making four.

The same principle applies to the number nine, which is written as IX.

There are six instances where subtraction is used:

I can be placed before V (5) and X (10) to make 4 and 9.

X can be placed before L (50) and C (100) to make 40 and 90.

C can be placed before D (500) and M (1000) to make 400 and 900.

To DO:

Given a range of values, convert all integers within the range (inclusive) to roman

numerals, printing them out with one roman numeral per line.

Convert all integers in the range from 1 to 3999 to roman numerals and them out with

one roman numeral per line.

Example of input/output:

enter two positive integers, smaller followed by larger:

2 6

Output should be roman numeral for all the integers in the range as:

II

III

IV

V

VI

1. List 5 examples of negative externalities DO NOT USE ANY EXAMPLE LISTED HERE (smoking, gun control, drinking, taxing, gasoline, aluminum, seat belts, people talking in class, students lying to teachers, professors who dont erase the whiteboard when done, parents who think whapping their kid is always the best and only way to discipline, bad roommates, k-12 teachers test memorization skills and suck the intellectual curiosity out of students ) discussed in either the textbook or the notes. For each example state the negative externality and state whether you believe government intervention would improve efficiency. a. List 5 examples of  positive externality DO NOT USE ANY EXAMPLE LISTED HERE (education, people talking in class about class material, good parents, alumni who make it big, public radio and television, fine arts, libraries, faculty research, moderate wine consumption,  ). For each example state the postive externality and state whether you believe the government internvention would improve efficiency.

Grade distribution: A statistics teacher claims that, on the average, 10% of her students get a grade of A, 24% get a B, 38% get a C, 18% get a D, and 10% get an F. The grades of a random sample of 100 students were recorded. The following table presents the results. A. Compute the expected frequencies B. List all of the grades which were given more often than expected separate by commas. The grades which were given more often than expected are: List all of the grades which were given less then expected, separate by commas. C. What is the value of x^2? D. How many degrees of freedom are there. E. State the null and alternate hypotheses. Below PA represents the probability of earning an A. H0= A=,B=,C=,D=,F=. tHE HYPOTHESIS TEST IS A = Part 7: Find the critical value of using 0.05 level of significance. Part 8: Determine whether to reject H0 Part 9: State a conclusion.

One cross-sectional study found that shingles was more common in lower socioeconomic status (SES) groups compared to higher SES groups. A later cohort study which analyzed the incident rate of shingles in both high and low SES groups found no difference among high and low SES groups. The difference in findings could most likely be explained by:

1. Information bias

2. the incidence-prevalence bias

3. the reverse-causality bias

4. 1) Information bias and 3) the reverse-causality bias

In an article in the Archives of Your Specialty, researchers report that screening Test T is enormously effective, and should be used routinely. As evidence, they report that the five-year survival rate of patientsS whose disease was discovered by screening with Test T is 90%, whereas the five-year survival rate of patients whose disease was discovered by other means is only 60%. However, in an article that same month in the Journal of the College of Your Specialty, another group of researchers report that screening with Test T has no effect. As evidence, they report that a study which randomized subjects to a program of routine screening with Test T or to no special screening regimen found an 80% five-year survival rate in both groups. The issue seems even more confusing because this second group of investigators acknowledges that if their data are reanalysed to compare the survival rate of subjects who actually followed the screening regimen to those who did not, whatever group they were assigned to, the cohort of those who actually were screened had five year survival of 85% whereas the cohort of those who were not had survival of only 75%. Despite this, these investigators maintain the position that no effect of screening has been demonstrated. Write a brief note for the General Practitioner's Quick Office Practice Digest, explaining why these various sets of results might be expected to in the way they do and advising whether or not to screen with Test T

An observational study is being designed to assess the association of alcohol intake with cardiovascular disease. Which of the following factors is likely to be a confounder? (choose one)

#Write a function called find_max_sales. find_max_sales will
#have one parameter: a list of tuples. Each tuple in the
#list will have two items: a string and an integer. The
#string will represent the name of a movie, and the integer
#will represent that movie's total ticket sales (in millions
#of dollars).
#
#The function should return the movie from the list that
#had the most sales. Return only the movie name, not the
#full tuple.

#Below are some lines of code that will test your function.
#You can change the value of the variable(s) to test your

In this python script find any bugs and errors which would cause the code to crash. The code must be re-written correctly.

After debugging make a separate list of all the errors you found in the script.
