4. An organization that strives to hold agencies accountable for truth in news reporting plans to select a random sample of 100 news stories from major U.S. news agencies in order to estimate the proportion of news stories produced by major U.S. news agencies that contain false information. A 90 percent confidence interval for the proportion of all news stories that contain false information will then be constructed. Before selecting the sample, the organization determines that they want to make the margin of error as small as possible. Which of the following is the best way for them to decrease the margin of error?
(A)Increase the confidence level to 95%.
(B)Increase the confidence level to 99%.
(C) Include a wider diversity of sources, such as local and international news agencies.
(D)Include news stories over a broad period of time, such as over the past decade.
(E) Increase the sample size.
Answer: E) Increase the sample size
Explanation: with the confidence level and sample proportion held constant, the margin of error will decrease as the sample size increases.
10. Lindsey is an avid tennis player. She kept track of the number of winners she had per game for an entire season. The shape of the distribution of the number of winners is roughly symmetric and the five- number summary of the number of winners is: Min: 10 Q1: 18 Med: 48 Q3: 79 Max: 92
Luke is Lindsey’s biggest rival. The average number of winners Luke had per game for the season has the same value as Lindsey’s IQR. Who had the greatest average number of winners this season? Explain.
(A)Lindsey, she averaged approximately 48 winners per game while Luke only averaged 18 winners per game.
(B)Lindsey, she averaged approximately 49.4 winners per game while Luke only averaged 48 winners per game.
(C)Luke, he averaged 61 winners per game while Lindsey only averaged approximately 48 winners per game.
(D)Luke, he averaged 61 winners per game while Lindsey only averaged approximately 79 winners per game.
(E)There is not enough information provided to determine Lindsey’s average.
