A marketing analyst at an e-commerce company is tracking the average daily website traffic. The company’s website typically receives an average of 86,000 visitors per day, with a standard deviation of 10,000 visitors. Last Saturday, the website recorded 85,000 visitors. What is the Z-score for Saturday’s website traffic? (Round your answer to two decimal places.)  

According to the Central Limit Theorem (CLT), what is the mean of the sampling distribution of the sample means?

With all other factors remaining constant, an increase in the population standard deviation will widen the confidence interval, not shorten it.

Coordination is defined as… (Select the best fit.)

The daily revenue at a USF bookstore has been recorded for the past five years. The mean daily revenue is $1,500. The standard deviation is $500. The distribution is skewed to the right due to high-volume days (e.g., beginning of the semester, football game days, graduation). Suppose a random sample of 100 days is selected, and the average daily revenue is computed. Which of the following describes the sampling distribution of the sample mean?

Increasing the confidence level from 95% to 99% will ______ the width of the confidence interval and ______ the precision of estimating the true population mean.

Roger Fenton was hired by the British government in 1855 to shoot photographs of the Crimean War in Europe. British war reporters had begun to send back frightening stories of British troops dying from bad medical care and cold weather. Criticism of the government increased. To cover up the facts, the government wanted Fenton to create scenes. Fenton produce over 350 pictures. He didn’t photograph any dead bodies or any actual battles. Instead, he shot photographs of groups of officers who looked proud, brave, and happy.              Not until 1862 did most people see true images of war. In that year, New York photograph Mathew Brady shocked Americans with photographs of dead Civil War soldiers. Brady was known for “getting the shot” on the battlefield. But he had a secret. He was nearly blind. Because he couldn’t see well, he hired 10 photographers who did the actual work on the battlefield. His team’s images were much more powerful than the posed portraits of soldiers that people had always seen. Brady and his team captured the feeling of dozens of Civil War battlefields just after the battles had ended. Even today, Brady’s images are a reminder of the war that nearly tore the United States apart.              Not only war, but other areas of life and society have been captured by photojournalists. In the 1879s, John Thomsonphotographed the lives of the poor working class in England. Jacob Riis, an immigrant to the U.S., photographed and wrote articles about the terrible living conditions of the poor in New York City. Lewis Hine traveled around the U.S. taking pictures of child laborers in mines and factories. During the Great Depression of the early 1900s, Dorothea Lange took pictures of farmers and farm workers to show the federal government how difficult life had become for these people.  These photographers used their pictures to help people and change society.Write 1, 2, or 3 in the box below.This article explainshow documentary photography developed.how photographs are made and printed.how to become a photojournalist.
