Refer to the North Valley Real Estate data, which report information on

Refer to the North Valley Real Estate data, which report information on homes sold during the last year. For the variable price, select an appropriate class interval and organize the selling prices into a frequency distribution. Write a brief report summarizing your findings. Be sure to answer the following questions in your report.

a. Around what values of price do the data tend to cluster?

b. Based on the frequency distribution, what is the typical selling price in the first class? What is the typical selling price in the last class?

c. Draw a cumulative relative frequency distribution. Using this distribution, 50% of the homes sold for what price or less? Estimate the lower price of the top 10% of homes sold. About what percent of the homes sold for less than $300,000?

d. Refer to the variable bedrooms. Draw a bar chart showing the number of homes sold with two, three, four, or more bedrooms. Write a description of the distribution.

Mark Lines is an online portal (www.marklines.com) that reports automotive industry data.

Mark Lines is an online portal (www.marklines.com) that reports automotive industry data. The table below shows the number of cars sold in the United States from January to November in 2017 and 2018. The top 22 manufacturers, plus others, are listed here. Sales data often is reported in this way to compare current sales to last year’s sales.

a. Using computer software, compare 2017 sales to the 2018 sales for each manufacturer by computing the difference. Make a list of the manufacturers that increased sales compared to 2017; make a list of manufacturers that decreased sales.

b. Using computer software, compare 2017 sales to 2018 sales for each manufacturer by computing the percentage change in sales. Make a list of the manufacturers in order of increasing percentage changes. Which manufacturers are in the top five in percentage change? Which manufacturers are in the bottom five in percentage change?

c. Using computer software, first sort the data using the 2018 year-to date sales. Then, design a bar graph to illustrate the 2017 and 2018 year-to-date sales for the top 10 manufacturers. Also, design a bar graph to illustrate the percentage change for the top 10 manufacturers. Compare these two graphs and prepare a brief written report.

Refer to the Baseball 2018 data that report information on the 30

Refer to the Baseball 2018 data that report information on the 30 Major League Baseball teams for the 2018 season. Create a frequency distribution for the Team Salary variable and answer the following questions.

a. What is the typical salary for a team? What is the range of the salaries?

b. Comment on the shape of the distribution. Does it appear that any of the teams have a salary that is out of line with the others?

c. Draw a cumulative relative frequency distribution of team salary. Using this distribution, 40% of the teams have a salary of less than what amount? About how many teams have a total salary of more than $205 million?

In the United States, the industrial revolution of the early 20th century

In the United States, the industrial revolution of the early 20th century changed farming by making it more efficient. For example, in 1910 U.S. farms used 24.2 million horses and mules and only about 1,000 tractors. By 1960, 4.6 million tractors were used and only 3.2 million horses and mules. An outcome of making farming more efficient is the reduction of the number of farms from over 6 million in 1920 to about 2.048 million farms in 2017. Listed below is the number of farms, in thousands, for each of the 50 states. Summarize the data and write a paragraph that describes your findings.
