The answer is: a line graph and a bar graph.

Explanation:

  • Line Graph: A line graph is an effective visual aid for showing changes over time. It can clearly illustrate trends in the number of homeless people in Chicago from 2000 to 2010, allowing the audience to see increases or decreases year by year.

  • Bar Graph: A bar graph is also useful for comparing quantities at different points in time. It can effectively display the number of homeless people in each year or at specific intervals, making it easy to compare the data visually.

  • Photograph: While a photograph can provide a visual representation of homelessness, it does not effectively convey statistical data or changes over time.

  • Flow Chart: A flow chart is typically used to show processes or steps in a sequence, not to display statistical data or changes over time. Therefore, it is not suitable for illustrating changes in the number of homeless people over a decade.

A researcher studies water clarity at the same location in a lake on the same dates during the course of a year and repeats the measurements on the same dates 5 years later. The researcher immerses a weighted disk painted black and white and measures the depth (in inches) at which it is no longer visible. The collected data is given in the table below. Complete parts (a) through (c) below. Observation 1 2 3 4 5 6 Date 1 / 25 3 / 19 5 / 30 7 / 3 9 / 13 11 / 7 Initial Depth, Xi 45.7 41.7 47.3 45.9 38.2 68.9 Depth Five Years Later, Yi 43.2 40.8 43.4 47.6 33.7 71.0 Determine the test statistic for this hypothesis test. (Round to two decimal places as needed.) Find the P -value for this hypothesis test. P-value = (Round to three decimal places as needed.)

The table provided below shows paired data for the heights of a certain country's presidents and their main opponents in the election campaign. Construct a scatterplot. Does there appear to be a correlation? Does there appear to be a correlation between the president's height and his opponent's height? A. Yes, there appears to be a correlation. As the president's height increases, his opponent's height decreases. B. Yes, there appears to be a correlation. The candidate with the highest height usually wins C. Yes, there appears to be a correlation. As the president's height increases, his opponent's height increases. D. No, there does not appear to be a correlation because there is no general pattern to the data.

Assume that the sample is a simple random sample obtained from a normally distributed population of IQ scores of statistics professors. Use the table below to find the minimum sample size needed to be 99% confident that the sample standard deviation s is within 40% of σ. Is this sample size practical? * To be 95% confident that s is within 1% 5% 10% 20% 30% 40% 50% * of the value of σ, the sample size n should be at least 19,205 768 192 48 21 12 8 * To be 99% confident that s is within 1% 5% 10% 20% 30% 40% 50% * of the value of σ, the sample size n should be at least 33,218 1,336 336 85 38 22 14 The minimum sample size needed is . Is this sample size practical? A. No, because the sample size is excessively large to be practical for most applications. B. No, because the sample size should be as small as possible for most applications. C. Yes, because the sample size should be as large as possible for most applications. D. Yes, because the sample size is small enough to be practical for most applications.

In the state where you live, the weekly unemployment compensation is 63% of the 26-week average for the two highest-salaried quarters. A quarter is three consecutive months. For January, February, and March, you earned a total of 33,000. In July, August, and September, you earned a total of 37,000. Determine your weekly unemployment compensation.
