Farmers know that driving heavy equipment on wet soil compresses the soil and injures future crops. Here are data on the "penetrability" of the same type of soil at two levels of compression. Penetrability is a measure of how much resistance plant roots will meet when they try to grow through the soil.
Compressed Soil:
2.85 3.082.6 2.822.95 2.782.82 2.982.76 3.002.81 2.782.78 2.963.08 2.902.94 3.182.86 3.16
Intermediate Soil:
3.13 3.543.32 3.363.1 3.183.40 3.123.38 3.863.14 2.923.18 3.463.26 3.442.96 3.623.02 4.26
Use the data, omitting the high outlier, to give a 96% confidence interval for the decrease in penetrability of compressed soil relative to intermediate soil. Compute degrees of freedom using the conservative method.Interval: To
Roman, a health data officer, was tasked to create a report describing the height of all the children ages 12-15 years in a small town in Rome. He measured the height of all the 37 children (ages 12-15 years) in that small town. Create a table showing the number and percentage of children ages 12 to 15 years according to sex.
The table shows a portion of the data for a sample of 51 private colleges and universities. The data include the name of the college or university, the year the institution was founded, the tuition and fees (not including room and board) for the most recent academic year, and the percentage of full-time, first-time bachelor’s degree-seeking undergraduate students who obtain their degree in 6 years or less (The World Almanac).
A. Prepare a scatter diagram to show the relationship between Tuition & Fees (in USD 1000s , on the horizontal axis) and % Graduate (on the vertical axis).

- Meghan is a psychology major who is testing a maze for a group of mice to navigate. In order for it to be productive for a class project, she would like the average time for a mouse to complete the maze to be 90 seconds. She randomly selects 28 mice and has each mouse complete the maze. Meghan records the time, in seconds, that each mouse needed to complete the maze. The results are provided in the accompanying data table. Based on research and previous results, Meghan assumes that the population is normally distributed and the population standard deviation is 5.80 seconds. Use Excel to test whether the mean amount of time a mouse completes the maze is 90 seconds, and then draw a conclusion in the context of the problem, where α=0.10.
